The Power of Exponential Growth OR Why you are not late

[Note: I shared this mental model with my email subscribers on Jan 15, 2017. If you want to receive a new mental model every week, join the club.]

Exponential Growth

I complain about this often. And I’ve heard others grumble in a similar vein. Whether entrepreneurs, technologists, scientists, economists, you name it – “I wish I was born when all the action was happening.”

But here’s the thing – as Kevin Kelly says in You are not late, you can bet that in 2045, someone will say the same thing about 2015.

The last 30 years have created a platform, from which ever new exciting things can result. Whether it’s AI, virtual reality, nanobots, etc. – it’s likely that the key technologies of 2045 will be very different from the ones today.

So, next time you complain about being too late to create Microsoft or Google or Facebook or string theory, read this. You are not late.

But the article also illustrates a larger point – the power of exponential growth.

What it is:

Exponential Growth - Bill Gates Quote

That’s the best summary of exponential growth I’ve seen. Our brains can think only incrementally. But technology improves exponentially. Advancements pile on each other.

For a long time, nothing seems to be happening. Then all of a sudden, hypergrowth.

I bet you’ll see the above graphic again and again. The last bit of shooting growth always astounds us. Despite it often being a mathematical certainty.

It’s not for nothing that Einstein (is rumored to have) said, “Compound interest is the 8th wonder of the world.”

 

Examples:

  • Moore’s Law: Gordon Moore’s prediction in 1975 that computing power would double every 18-24 months [I paraphrase] has held remarkably true. This regular doubling has given us PCs, mobiles, smartphones, and now AI.
  • Adoption rates of consumer technologies: As this graph shows, adoption rates of consumer technologies are ever-accelerating.
  • Look at any of the major growth stories of the last few years – Uber, Airbnb, etc. In each new market, they started small. No one noticed them, or worse, they dismissed them as irrelevant, non-scalable, or playthings of the rich. Till, suddenly, their dad started using them.

 

Rules to follow:

  1. When planning your career, try to work in sectors that are growing exponentially. Growth creates options.
  2. Don’t skate to where the puck is. Skate to where it will be. To requisition Wayne Gretzky’s memorable words, go where the future will be. Build skills that will be useful tomorrow.

Bottomline: The future will always be more different from today than today is from the past. The future adds a zero.

Ergo, the best time to start something new is NOW.

The Pareto Principle and the Minimum Effective Dose

[Note: I shared this mental model with my email subscribers on Dec 11, 2016. If you want to receive a new mental model every week, join the club.]

 

Out of more than 120 wholesale customers, a mere 5 were bringing in 95% of the revenue. I was spending 98% of my time chasing the remainder. – Tim Ferriss, Four Hour Work Week

What it is:

Most of us are familiar with the Pareto Principle. 80% of your sales come from 20% of your clients. 20% of people produce 80% of your enjoyment and propel you forward. But 20% produce 80% of your anger too.

A few factors have disproportionate influence.

Some of us are also familiar with Pareto’s more extreme cousin – the power law.

But fewer of us make the jump to its immediate corollary – the Minimum Effective Dose (MED). 

 

I first came across this in Tim Ferriss’ books. He defines it as “the smallest dose that will produce the desired outcome”.

The logic goes – if 20% of tasks produce 80% of the results, then you need to focus only on this 20%. In most avenues of life, where perfection is not the goal, this 20% is all you need to be effective.

This was one of the big ideas of 2015 for me. It transformed how I think. See more here.

Minimum Effective Dose

The Minimum Effective Dose (MED)

Examples:

  • MED in business: Whether your customers, your vendors, or your advertising – choose the few that give you the most value, and forget about the rest.
  • MED in daily productivity: What’s the no. 1 most important task of your day. Do that first. (“Minimum Viable Day”, anyone?).
  • MED in health: Stop eating white carbs. See Tim Ferriss’ slow carb diet, or Gary Taubes’ Why we get fat. (But maybe I’m oversimplifying – I’m not a health expert).

Rules to follow:

  1. Identify which tasks have the most impact on your objective.
  2. Focus on them. Forget about the rest.

This suddenly reminded me of Warren Buffett’s Two List strategy.

Winners don’t do things differently. They do different things.

No, I haven’t made a typo in the title. The age old saying “Winners don’t do different things. They do things differently.”, made famous by Shiv Khera in his book You Can Win, is wrong.

I remember when the book came out, everyone quoted it as gospel. Every individual can be great. All you need to do is work hard, and work smart. And they would all nod knowingly at the last clause. So that’s what I did – studied hard, went to a good B-School, got a great job and worked hard (and smart) there.

Pic00003

But unfortunately, this saying isn’t true. And it’s becoming more false as technology eats the world (to co-opt Marc Andreessen’s pet phrase).

 

This mentality of doing things smarter now pervades all aspects of our life. But it suffers from one fallacy – what I call ‘focusing on the numerator’.

It’s like a company that focuses only on improving its profit margin. It brings in cutting-edge efficient machines, implements Just-in-time production techniques, and what have you. But with all these productivity improvements, how much could the profit margin increase? From 15% to 20%? 40%? 100%??

Even in the best (and impossible) scenario, the upside is capped at 100% of revenue. What if you focused, instead, on the denominator? What if you looked for ways to achieve a step jump in revenue? Suddenly, there’s far more value to capture, even if you are inefficient.

 

What you work on matters, and matters far, far more than how hard you work. This is an example of a Power law, which I’ve written about before.  In the early 1900s in England, there was a profession of people called ‘knocker-uppers’ (no, it’s not what you think). Their task was to wake people up every morning. They would walk the streets with a long stick, and tap on windows till people woke up. Many of them worked hard. I’m sure they worked smart too – with well-balanced, aerodynamic and sonorous sticks. Still, they lost their livelihoods in a jiffy when alarm clocks came into the market.

Moral of the story: Do more valuable tasks, instead of doing less valuable tasks efficiently or smartly. Doing something unimportant well does not make it important.

Pic00001

This is how the world is today – it’s the new normal. The companies that win are the ones that innovate 10X and ‘change the game’. Not the ones who innovate incrementally. As Peter Thiel says in his book, don’t move an industry to greater efficiencies (i.e., from 1 to 1.1). Focus instead on moving something from zero to one.

Look at the biggest companies around us – Google (search advertising), Apple (iPhone), Amazon (e-commerce, e-books, etc.). They didn’t just improve search algorithms, build a better phone, or sell books through a simpler distribution chain. They revolutionized their respective industries. Not by doing things differently or more efficiently, but by doing different things.

And it’s not just companies – it’s visible in every aspect of life. No longer can you say, “Karm kar, phal ki chinta na kar” (“Work hard, don’t worry about the result”) in all honesty. If the recipe sucks, it doesn’t matter how good a cook you are.

This may be bad news. But it’s good news as well. Once you start looking for this ‘focus on the numerator’ behavior everywhere, you can make more valuable decisions about your company, your products, and your time.

A few examples of the implications, off the top of my head:

  1. Product Management: Instead of A/B testing and optimizing your nth new feature, focus on getting more people to use your product. Andrew Chen puts this well in a recent article.
  2. HR: Instead of trying to getting the best out of your team, learn how to build a better team. [This is more important in technology businesses, and less so in traditional brick-and-mortar companies.]
  3. Health: You can try to manage your cholesterol by eating french fries cooked in refined oil or unsaturated oil or whatever the flavor of the season is. Or, you can just stop eating french fries!
  4. Personal Finance: Focus on earning more, not spending less. A direct corollary of the revenue-profit point I made earlier. It’s ironic, but I’m the prime target for this lesson. As a Tam-Brahm, I started expense budgeting almost before I could walk. I’ve spent countless hours balancing my expenses, tracking my receipts, and strategizing lower spends, when I could have instead focused on doing more valuable things. Which means anything else, basically.
  5. Personal Productivity: Be effective, not efficient, as Tim Ferriss says in The Four Hour Work Week. Do two important things, instead of 10 unimportant ones. Again, a slap on my face – so far, I was firmly in the ‘get more out of your day‘ brigade.

TL:DR: In work as in life, we should strive hard by all means. But we must think hard first – is what I’m doing the most valuable thing I could do? Let’s build more important things, instead of optimizing our lives away.

The reading list that transformed my professional life

Bookshelf_Small

6-9 months ago, when everyone was posting lists of the top 10 books they read, I was unfortunately busy with work. And then, when I wanted to post my own list, it was much too late to do so – people had moved on to sharing Upworthy articles instead.

Nevertheless, what’s far more useful is to talk about the top things I learnt from books – the ideas, insights, stories that changed how I think about life and work. After all, that’s why you read books – to improve yourself in some way – isn’t it? Well, at least all books apart from the Twilight series.

So, here are the 5 ideas that transformed how I think about life and work, and the books I read them in. Rather than describing these ideas in detail, I’ll also share links to articles that offer a short version. But I would definitely recommend you read the book themselves too!

 

1. System 1 vs. System 2 Thinking – Thinking Fast & Slow

An understanding of psychology is, in my view, an essential skill for anyone whose daily life involves interactions with other people to get stuff done. The human mind is not only not rational, it is also irrational in a few consistent and repeatable ways. Understanding these cognitive biases and fallacies that we suffer from can go a long way in helping you get what you want in interactions with people.

One of the key concepts I’ve come across in this area is that the human mind is really two distinct personalities – let’s call them System 1 and System 2. System 1 is the more automatic, quick-and-dirty, heuristic based, lazy thinker – get to an answer quickly by applying habits and patterns, often at a subliminal level. System 2, on the other hand, applies more careful, overt deliberation to any problem, coming to a solution in a more considered manner.

At any time, you’re thinking in one of these two modes. For example, when you’re doing math, you’re carefully thinking of the problem and solution – that’s System 2 in operation. When you’re tying your shoelaces, you’re usually not thinking about the loops and knots actively – you just do it. That’s an example of a System 1 task.

Now, at most times, the mind defaults to System 1 – which tries to recognize and apply patterns without thinking too much. And the result is that it can get tricked in fairly predictable ways – what we call cognitive biases. Two examples of these are anchoring (where an initial number suggested to you often influences your answers to a numerical question) and availability bias (you tend to overestimate the probability of an event if you can remember examples – this sometimes results in people paying more for earthquake insurance than insurance for natural calamities – even though the latter includes earthquakes!). Won’t go into detail on these biases here – you can read the articles I’ve linked to, and the book. But I’ll blog about them soon too!

Another interesting implication of the dominance of System 1 is that you can trick your brain into certain emotions. For example, you know that when you’re happy, you tend to smile. But did you know that this can work in reverse – that you can trick your brain into happiness, by simply smiling? This was a ridiculously amazing insight for me – to know that causality works both ways, and I can control my emotions. I’m a ‘moist robot’, in Scott Adams’ words.

Book: Thinking Fast & Slow – one of the best books I’ve read – and I actually prefer fiction.

2. Making Skewed Bets – Fooled by Randomness & Antifragile

When I was in business school, I read Fooled by Randomness, by Nassim Taleb. At that point, I thought it was the best book I had ever read – so many brilliant ideas, one after the other. I read it again recently, and while I’m a little less effusive, it’s definitely worth a read – it’s long-winded and unnecessarily complicated in parts, and the language is often self-absorbed – but if you can look beyond that, the insights will hit you at an unrelenting pace.

But the most important insight for me – in that it almost exclusively governs my world view since I read it – is that of making skewed bets. The world is innately random – your success depends far more on your luck than on your ability. At first glance, this seems to encourage laziness. Why work hard when your destiny doesn’t depend on it? But looking deeper, the implication is that you should try and expose yourself to ‘positive’ luck as far as possible, while limiting the impact of ‘negative’ luck. In simpler terms, expose yourself to very high upside, while limiting your downside as far as possible.

This is called making a skewed bet – where if you win, the gains are a windfall; but if you lose, you don’t lose that much. A lot like financial options or a startup – if you make it, you make it. And if you fail, then your losses are limited – the cost of the option, 1 year of salary, etc. Of course, the probability of a loss may be 90%. But if you make 10 skewed bets, then you’ll make a windfall gain on 1 of them – and that may be more than enough.

Another important way to keep yourself open to good luck is by simply staying on the field. Thomas Edison got the light bulb right on his 1000th attempt – and that happened only because he kept trying different things, and didn’t give up after 999. To surf a ‘killer wave’, you need to first be in the sea, navigating the 100 tepid waves before.

Book: Fooled by Randomness. Antifragile, a subsequent book by Taleb (even better), actually takes this one idea and distills it far more.

3. Goals vs. Systems / Success as a process- How to fail at almost everything & still win big

Taking the previous point further – success, then, seems to be a process rather than a brilliant idea, inch-perfect execution or just good luck. Try a lot of different things, observe, learn, and iterate. So that you slowly, over time, collect all the right materials for the magnifying glass of luck to ignite. You do all the right things and keep improving, so that when Lady Luck knocks, you’re ready.

Success is therefore a system (take several skewed, high-reward/low-cost risks), rather than a goal (I want to get rich). Now that’s at a macro-level, but this makes sense even at the micro-level – rather than adopting a goal of doubling your user base and throwing money at it, take a systematic approach of trying different things, observing, and then betting the farm on the 2-3 marketing techniques that work.

Scott Adams (of Dilbert fame) carefully charts out this approach in his book.

Book: How to fail at almost everything & still win big. I would venture that this is one of the best and most actionable books I’ve read. But read at your own peril – as they say, one should be careful when taking life and business advice from a cartoonist.

4. Power Laws, or why working hard is not enough – Zero to One

I’ve already blogged about this here, but it’s worth reiterating. Today’s business world is not a normal distribution, with most people distributed around average payoffs. Rather, it’s an exponential distribution – very few companies will make most of the money to be made. Therefore, success depends far, far more on what you do, than on how you do it.

random-vs-power-law-distribution-2

In a power law distribution, very few sample points account for a majority of the population’s value.

The power law will permeate all your decisions (e.g., one marketing hack will drive 90% of your traction, one product feature will drive 90% of repeat users, etc.). Won’t go into more detail here – definitely read the post!

5. Attractor States Good Strategy Bad Strategy

The previous three concepts have all been around the idea of work and success. This one is different, and is a tool that I’ve found quite useful in jump-starting creative thinking about problems.

Let’s say you’re trying to think of a startup idea in a given space. You could look at what users do now, what they buy, how they consume, etc., and try to find areas where you can add value. Or, you can look at how the industry will inevitably evolve in the future and see how you can accelerate that.

The author calls this concept an ‘attractor state’ – given industry trends today, what do you see as the logical next frontier over the next 10-20 years? And how can you participate in that, rather than making incremental changes to the status quo? To paraphrase Wayne Gretzky, the ice hockey legend – don’t skate to where the puck is, but to where it will be.

This is a slightly nebulous concept, so let me provide an example. Let’s say I want to create an offering in the payments space. One option is to join the crowded current market, and provide a mobile wallet solution, a payment gateway, etc. Another way is to think of where the industry will be in 10-20 years – its attractor state. I’m not a payments expert, but seeing how it has evolved over time (barter -> gold -> paper money -> credit cards -> mobile wallets), there’s a clear trend towards individualization. The reasons mobile wallets are a great innovation is that everyone carries a mobile today, and they don’t share mobiles – it is a unique identifier of a person. Taking this individualization further, the next wave of advancement has to be biometrics – where unique characteristics of your person (iris, voice patterns, fingerprints, etc.) are your identifier, based on which transactions can be completed from your account. You don’t need to whip out your phone or credit card – just staring at a tiny lens is enough to connect to your payment account.

How does this help an entrepreneur? With this end-game in view, entrepreneurs can think about how they can add (and capture) disproportionate value in the long-term – the products and services they can start building today, to accelerate the attractor state. In the case of payments, it could be future biometric sensors, systems for collating massive customer data, POS terminals for accepting payments, etc. – each of these possibilities could be game-changing.

Won’t go into much more detail here – but I’ll write a blog post or two on this concept soon. I find it an incredibly powerful way to improve your creativity when thinking about problems and solutions.

Book: Good strategy Bad Strategy. Apart from a discussion of attractor states, this book also has a great discussion of chain linked strategy and focus as a source of competitive leverage. I’ve blogged about this here.

Further Reading: Will write a detailed post on this soon!


These are the five concepts from books that changed my world-view. It may be asking too much to hope that they fundamentally alter your thinking too, but I hope you find these perspectives and books interesting. Do comment!

The Power Law, or why working hard is not enough

hard work

Throughout your academic life, you’re told, variously, “There’s no substitute for hard work”, “Work hard and don’t think about the results. They’ll take care of themselves”, “It doesn’t matter what you do, as long as you do it well”, and so on. Mildly put, that’s completely false.

I read Peter Thiel’s Zero to One a couple of months ago. In this book, Thiel, who founded Paypal and has backed many successful startups (including Facebook), talks about startups and how to create value in the world. The book itself has many highs and lows, but I found his discussion of power laws very thought provoking.

 

So, what is a power law? A power law describes an exponential distribution – where a few individual points account for a majority of the value in the population. Simply put, it’s the Pareto principle (80:20) on steroids:

random-vs-power-law-distribution-2

Normal distributions assume that the entire population will be distributed across, with a huge majority of people around the average. For example, if you were to plot a distribution of the weights of a country’s entire adult population, it would probably resemble a normal distribution – a large proportion of people near the average, and the no. of people going down as you moved away from the average on either side.

On the other hand, populations that obey a power law are completely skewed to one side. Think about wealth distribution – you know how they bandy around the statistic that 1% of people account for 50% of the world’s wealth? That’s a power law. I read somewhere that whenever a book from Chetan Bhagat is released, it almost outsells the next 500 best-selling books combined. I was quite surprised, but I shouldn’t have been – book sales also follow a power law.

Why is this important? Power laws have always played a huge part in nature. For example, a vast majority of earthquakes are relatively minor, but a tiny proportion cause almost all the damage – that’s a power law. They also explain a lot of our societal context – language (a few words dominate usage), city populations (the largest cities account for an inordinate proportion of urban population), and so on. And more and more, entire industries are beginning to resemble power laws – especially in the Internet era. Think Search (Google accounts for 88% of the market), Social Media (Facebook has 33x the no. of visits as Twitter, its nearest competitor) and so on. This phenomenon, where the winner takes (almost) all, is becoming more and more pervasive. You dominate or you die (separate post on this later).

But coming back to the main focus of this post, what does this mean for you as an individual? A few things, actually:

  1. What you work on matters, and matters far, far more than how hard you work. Till the early 1900s, there were people called ‘knocker-uppers’ who would help people wake up every morning, by walking down the street with a long stick and tapping windows till people woke up. Many of them worked very hard; but lost their living in a jiffy once alarm clocks started being mass-produced around 1920. As Thiel says, by all means work very hard on what you’re good at, but first think hard about whether it will be valuable in the future. In a world where the returns on your efforts follow a power law, you must think hard about where you stand on the curve.
  2. If you want to start up, seriously consider working for another one (with stake / options). One of the corollaries of the power law is that very few startups will succeed, but they will succeed hugely, enormously. So, being at the right startup is far more important than your role in the startup and how much stock you own. A little simplistically, 0.01% of Google is probably worth a lot, lot more (35 million dollars) than 100% of a startup that you’ll start. And most startups fail, in which case you’ll own 100% of nothing. So if there’s another startup / early stage company that you think is promising, it may actually be a better bet to join it with stock / options than starting your own.
  3. If you have a startup already, don’t hoard stake. Many startup founders are very miserly with stake. I’ve heard many say “Your company’s stock is the most valuable thing at your company.” While technically true, many take this to mean that you should give away as little stake as possible. Rather, I’d read this as meaning that you should do whatever you can to raise its value. And if a particular investor can actually help you succeed and raise the value of your company significantly, then giving them slightly higher stake (within limits, of course) is worth it. This is especially the case early on, when the growth in the pie will affect your personal shareholding’s value far more than the proportion of the pie that you own.
  4. Realize that the power law will permeate all your decisions. Whether the markets you choose to play in, your distribution channels, your product features or your decisions themselves, few or one will dominate in terms of creating value for you.

Now, you can’t predict the future, and so you don’t know which of your choices will matter. The only way to set yourself up for breakout success in an uncertain world is to go for the big prize – where even if chances of success may be low, the value created (for you and others) in the event of success is immense.

 

These are the different ways in which power laws affect us as individuals. I would love your feedback – how else do you think power laws affect our daily lives and work?
