The thing about first principles thinking is that nobody tells you about the part where the car jerks.
They tell you about the elegance of it — stripping a problem to its foundations, reasoning from bedrock rather than convention, arriving at understanding through logic rather than instruction. They make it sound clean. What they don't mention is that there is always a gap between understanding a thing correctly and executing it smoothly, and that gap tends to make itself known at the most inopportune possible moment. In my case, the moment was a busy Bangalore street in 2003, with a girl in the passenger seat who was paying very close attention.
But I'm getting ahead of myself. Let me start with the gears.
I grew up around men who spoke about cars the way other men spoke about cricket — with authority, with statistics, with the casual fluency of people who assumed everyone shared their reference points. Top gear. First gear. Zero to sixty. The numbers moved through conversations like a private language I was supposed to already speak, and I didn't, and I couldn't ask because asking would have revealed the gap.
The specific confusion was this: I could not understand why gears made a car go faster. The logic seemed to contradict itself depending on who was talking. First gear could make you fast, someone would say. But fourth gear was faster, someone else would insist. I turned this over in my mind for longer than I would like to admit — not because I was slow, but because I was trying to understand the principle underneath the claim, and nobody was offering the principle. They were offering the conclusion and expecting me to accept it.
I didn't accept conclusions I couldn't trace to their source. I never have.
The problem was there was no Google. No YouTube video demonstrating gear mechanics in slow motion. No forum where someone had already asked this exact question. There was only the world around me and whatever I could reason from the things in it.
Then I looked at my bicycle.
A bicycle with gears is a much more honest machine than a car. You can see everything. The chain, the cogs, the direct relationship between what your legs do and what the wheels do in response. No engine obscuring the principle, no bonnet hiding the mechanics. Just the naked truth of how force becomes motion.
And on the bicycle, the pattern became clear.
In a lower gear, each revolution of the pedals moved the wheel a shorter distance — but it required less force, which meant your legs could keep spinning even when the terrain was hard. Uphill, or from a standing start. In a higher gear, each revolution covered more ground, but it demanded more force, more momentum already in the system. You couldn't start in a high gear. You built to it.
I sat with this for a while. Then I transferred it.
The engine was the legs. The gearbox was the cog system. First gear gave you torque — the force to move a heavy object from stillness, to climb, to push against resistance. Higher gears converted that accumulated momentum into sustained speed on flat ground. You couldn't start in top gear any more than you could start cycling uphill in your highest setting. You built through the sequence. The system wasn't contradictory. It was perfectly logical, and nobody had thought to explain it that way because to them it was obvious, absorbed through years of use rather than arrived at through thought.
I had arrived at it through thought. Without a single lesson.
My father had given me perhaps two hours in a field sometime before this — him controlling the clutch and the brakes, me touching the steering wheel, getting a vague sense of the machine's responses without truly being responsible for any of them. That was the sum total of my formal driving education.
In 2003 I paid ₹20,000 cash for a second-hand Maruti Suzuki. The number plate was GGG787. I remember the number because I stood in front of the car after the transaction was complete and looked at it for a moment — this object that was now mine, that I was now responsible for, that I was now going to drive — and the number plate was what my eyes landed on.
I found a busy street. This detail matters: I did not find a quiet lane, an empty car park, a forgiving stretch of open road. I found a busy street, because the busy street was where the car was, and I had already decided.
I reversed out — slowly, steering right, committed to the geometry I had worked out in my head. First gear. I kept it in first gear for longer than a trained driver would have, because in first gear the car was controllable, the principle was manageable, the gap between theory and practice was narrowest. I did not go fast. I went.
I did not hit anyone. I did not stall. The car moved, and I moved it, and somewhere on that busy Bangalore street I understood that the bicycle had told me the truth.
Here is where I should probably end the story, with the clean conclusion that first principles thinking works, that knowledge earned through reasoning is as valid as knowledge earned through instruction, that you can teach yourself anything if you understand the underlying structure.
But that would leave out the girl.
There was a girl. I was twenty, I had a car, and there was a girl I wanted to impress. I want to be honest about this because it is important to the story's accuracy: the first principles thinking was genuine, the self-taught driving was real, and the fuel underneath all of it, on the day it mattered most, was that I wanted her to see this. The theory would have stayed theory without that specific motivation giving it a deadline.
I picked her up. Kaakha Kaakha was playing — Harris Jayaraj, that score that makes you feel like the protagonist of something significant. I was twenty years old in a ₹20,000 Maruti Suzuki and I had reasoned my way into the driver's seat without a single lesson and the music was exactly right for the person I was pretending to already be.
The car jerked.
Not once. Several times. The clutch-to-accelerator balance that lives in the hands and feet of experienced drivers — that particular muscle memory that cannot be derived from first principles alone but must be earned through repetition — was not yet mine. The car announced this clearly, emphatically, and in front of a witness.
She knew immediately. Of course she knew. You cannot mistake a learner's jerking clutch for anything other than what it is.
I ignored it completely. Did not acknowledge it, did not apologise for it, did not break character. Just kept driving, kept my eyes on the road, kept the music playing, kept being the version of myself I had decided to be on this particular afternoon.
I think about this often when I am in the early stages of something new — a platform, a strategy, a system I have reasoned my way into but not yet executed smoothly. There is always a jerking phase. The theory is correct, the principles are sound, and the execution announces your inexperience to anyone paying close attention.
The question is not whether this phase exists. It always exists. The question is whether you ignore it and keep driving, or whether you pull over and apologise for it.
I have never once pulled over to apologise for the jerking.
First principles gets you to the road. The road teaches you the rest.
The car eventually stopped jerking. She stayed in the passenger seat. And somewhere in that sequence — in the commitment to the principle even while the execution was imperfect and embarrassing and completely visible — I learned something about how I would approach every difficult thing that came after.
You understand the mechanism. You get in. You drive.
The smoothness comes later.
