How much of career and startup success is luck versus deliberately engineered?

Paul Graham · published May 2004 · hedged

Startup payoff is only proportionate to productivity on average: the mean may be 30x but the median is probably zero, because most startups fail.

There is a large random multiplier in any company's success; it's common for a startup with a genuinely good product to take slightly too long, run out of money, and shut down.

Startups are an all-or-nothing proposition, and you generally don't know which outcome you'll get until the last minute.

Like a mosquito, a startup wastes no energy on defense and is designed only to score; Viaweb's trajectory was a sine wave and it came close to tanking several times.

There is no arrangement available in business that lets you simply work extremely hard for a guaranteed large payoff without the lottery attached.

Viaweb's risk-averse hackers would have preferred a 100% chance of $1 million to a 20% chance of $10 million, but no such deal exists.

Microsoft's dominance rested on IBM's blunder in the DOS licensing deal; had IBM demanded an exclusive license Microsoft would still have signed and IBM could easily have obtained an operating system elsewhere.

Microsoft at that stage was effectively a component supplier with little leverage over IBM, so IBM gave away control of the PC standard; afterward Microsoft only had to execute.

Hackers underestimate luck because they come from a world where skill is paramount; the better model is that outcome is the product of skill, determination and luck, so zero luck yields zero.

Great work is the product — in the literal multiplicative sense — of ability, interest, effort and luck, which reduces the practical problem to finding work where your ability and interest combine, and there are grounds for optimism that a comically close match exists.

Luck can't be influenced and effort can be assumed if you want great work, leaving ability and interest; given the huge and still-expanding variety of kinds of work, the one you're best suited for is probably a very close match, discoverable only by trying.

source Great work is the product of ability interest effort and luck so the task is finding work where ability and interest closely match
