Luck is a lagging measure. It often takes years to connect cause and effect, so most don’t bother. You publish an essay in 2022—it brings you an investor in 2025. You make an introduction in 2025 — it brings you an introduction in 2027. The lag makes it hard to motivate yourself to do it because you don’t know when the return will be. My friend Ben Levy solves this by tracking luck inputs: introductions made, people helped, or bets placed. He trusts that if he maintains a high luck input rate, the luck outputs take care of themselves. You can’t control the timing of luck, but you can control the volume of luck inputs you create.
