We make choices every day, like what to eat for lunch. Once in a while, we make major life choices: where to live, and where to work.
Life choices feels like we’re ordering from a menu. I’ll have… mm, living in Houston, and a job at NASA please. Obviously, that’s not how it works. Choosing is not always an active thing, and not all choices are available to us. One such life choice happened when I was 18… I “chose” to not go to Cambridge and went to NUS instead for undergrad.
I was good at maths when I was a teenager, but only certain kinds of maths. Like trigonometry and complex numbers. I was bad at things like number theory, which was essential to do well in a Maths Olympiad.
My school held a mock Olympiad to select people to train for the Singapore National Maths Olympiad. I placed #47, and was deemed unworthy of investment. This was Raffles Junior College, and I didn’t quite appreciate how smart everyone else was. It was the kind of school that brought back gold medals from the International Maths Olympiad.
Despite this, I filled in “Maths” for the course I wanted to apply for in my application to Cambridge University. An old, white guy flew down to Singapore to interview prospective applicants.
That interview was one of the highlights of my teenage years, because I got really lucky with the question. They cleared out the (usually very busy) library for the interviews. After a very long walk through rows of empty desks and bookshelves, I finally came face to face with the pointy-nosed chap from Cambridge.
He looked over his half moon spectacles and lobbed me a maths problem that involved solving a cubic equation with complex number roots. There was pen and paper on the desk. I worked through the problem verbally, and solved it in conversation. I don’t remember how long it took because the mind plays tricks… ten seconds?
You keep your pen and paper, sir, I don’t need stationery to do your maths.
The mouth of Cambridge face went like an O. I don’t remember much after that, and I walked out feeling like I had aced it. This happened before my final A-level exams, so I hadn’t had a “standardized” test or grade yet. I got a conditional offer to join Trinity College, subject to my final A-level results. Step aside Issac Newton, there’s a new kid in town.
Now, between this Cambridge interview and my A-level exams, I met a girl. I was in love, and we spent a lot of time together. My A-levels didn’t go well.
One day, when I was sitting at home in Hyderabad, I got a letter in the post. After reviewing my grades, Cambridge decided that there wasn’t a place for me after all. I was on the waitlist. My mother was with me when I opened the letter.
Oh well, I said. It doesn’t matter because I can’t afford to pay fees anyway. My grades were not good enough for Singapore government scholarships, which was the only funding source that I knew of.
My mother was reading a newspaper at the time, and it had an article about Infosys. This was 2002, and now you know how old I am. Narayan Murthy, the founder of Infosys, was a newly minted tech billionaire.
My mother said: Why don’t you ask Narayan Murthy if he will fund your education?
I thought, what! What an nutty idea. Yeah, maybe, I mean… what would I do? Write a letter? Noooo. Who does that!
I went to NUS and my life took it’s own path.
Had any single one of these events not happened, my life would have turned out different. That’s a lot of mouthy words, it’s better represented in a diagram.
The dotted lines are alternative futures that could have happened, but didn’t. They could be regrets, they could be just idle musings. This isn’t about quantum physics and the many-worlds interpretation. I don’t really care if there’s a version of me that did, in fact, write to Narayan Murthy, and I went to Cambridge. That version is not me, it is a theoretical curiosity.
This other version probably ended up in a bank and is some sort of finance dickhead who drools at market alphas. Dodged a bullet there. I am who I am, because of the choices I did make… and because of the choices that I didn’t.
Events happen, and choices push us down a specific path.
The tree of our life
This set of circumstances happened to be available to me, and some of it was forced i.e. not really a ‘choice’. Cambridge rescinding my offer was a forced choice. We can think of choices as anything that pushes us down a specific path, when multiple paths exist. Choices are not necessarily active. In fact, they can be passive. And we make a lot less active choices than we imagine.
Active and passive are big words, so let’s ground this in feelings.
When it feels like we’re ordering from a menu, it’s an active choice. If we have two job offers and have to choose one, for example. If it feels like we’re flowing and flitting about in the wind, choices are being made for us.
Our tree is unique to our life context. We all have different contexts, because we are different people. Where we live, the people we hang out with, how much money we have, whether we have kids, or a mortgage, our political views, whether we are in a fulfilling relationship, the entertainment we consume— all create a unique life context.
We can plan for things, but mostly our context is just there. Invisible. We only feel it through events and our choices.
Our life context, combined with who we are, makes our tree. Our tree is bigger than the path we take through it; it represents the opportunity space for our lives. There’s the tree itself, and how we traverse it. Choices are how we traverse our life tree.
Forced choices is the reduction of possibilities. Even though the other paths are available in theory, we cannot take them. We can think of this as narrowing the tree. Take, for example, what happens if we take on mortgage debt to purchase a house.
It is unlikely that we will quit our job and start doing standup comedy gigs, unless we have enough money to cover the mortgage debt. The fact that we have taken on this debt reduces the possibilities available to us.
Tree templates
Making choices, especially big life-changing ones, is a difficult process. The easiest way to do it is to borrow ideas from someone else’s traversal of their life tree. My father worked his entire working life in a government-owned engineering company, slowly rising through the ranks over forty years. This intuitively felt like a bad idea for me. I had to find my own way to traverse my life tree.
The least stressful and stable strategy is to go on the path that is well understood and has a template. All of us subscribe to at least some templates. We have to, in order to survive in our social systems. Most of us go to school, open a bank account and agree that killing someone is a bad idea.
Some templates we can choose to reject. But the rejection of a template comes at a price. Deciding not to get married makes moving countries much more difficult, if one of the partners needs to get a dependent visa. A piece of paper that bestows a legal status on a relationship makes some things easier.
Spending three months of salary on a diamond engagement ring was the work of a Don Draper-like figure in the advertising machinery of the diamond industry. Such expectations form templates for our choices, and these templates are everywhere.
Templates are not a bad thing, necessarily, because they reduce existential angst.
Bring Your Own Tree
But, you say… I will create my own path, blaze my own trail through the tree! Great, welcome to free will, or at least the illusion of it. You are also taking on a higher cognitive load to figure out your life. Imagine going through life without a bank account, or a card. It’s harder to do, so it better be worth it.
Actively rejecting templates for traversing the tree of life means that we are faced with greater uncertainty, and are more precarious than those who accept and follow a template. Clouds of uncertainty loom over our choices because we have rejected templates. The clouds remain, no matter how much we think about these choices before we make them.
Templates result in narrow trees. If we don’t want to follow a template, it would make sense to try to broaden our life tree as much as possible. A broader tree means more available choices, and increases the chance that we traverse a path that does not fit a template. A path that works for us, is unique to us.
Narrow trees are good, because going through life in a narrow tree means that you don’t have to think about choices so much. The only source of stress and frustration is that the tree is not broad enough i.e. we don’t have more choices.
I eat spaghetti carbonara at Italian restaurants. Every time. There are lots of choices but I ignore them because I am comfortable with a narrow tree.
Broadening a life tree is not necessarily an explicit action to take. Sometimes, we may only need to identify the choices that will narrow our life tree, i.e. result in less choices, and avoid them. If we choose to actively think about how to maximise the choices available to us, we can try to deliberately construct our life context to allow for broadening of our life tree.
People rent homes despite being able to afford to buy one, because it gives us more flexibility. This is broadening of the tree. Broadening can (and should) be selectively applied to different areas of our lives.
Navigating broad trees
One way to broaden a tree is to make active, risky choices.
Risky choices are scary, because why take a risk? Risks are stupid. The riskiest choice is the choice that we know least about, and hence are unable to predict its outcome. We can tell when a choice is risky if we cannot logic our way into clarity.
Risk is the absence of information, not probability of success.
Traversing the riskiest path allows us to gain more information, because it may put us in different contexts where we meet people, get exposed to new ideas or change our physical environment. A strategy that traverses the riskiest path is a strategy that maximizes new information. Doing this all the time is not a great idea unless we love instability.
There isn’t a right way to traverse our tree. Living with a very broad tree is debilitating, because we are in flux. We are constantly in exploration mode, and not in exploitation mode. We have to find the balance, just like a contextual bandit algorithm does. Sometimes we broaden, then we narrow, then we broaden again.
Broadening can be uncomfortable; we are operating out of our comfort zone. But we feel alive, because information-heavy experiences are richer. If done right, we have a better chance to reject templates for traversing the tree of life.
Be ready to be constantly uncomfortable. Be comfortable with uncertainty.
I first wrote this three years ago (late 2019), to explain my approach to choices to a friend. I think I go through life with the broadest possible tree that I can handle at any given time. It’s not fun. And then I find myself wanting a narrow tree. And then I feel like life is boring. Then I want to broaden the tree. Then I feel like I need to ‘grow up’
