Attention is your scarcest resource | Ben Kuhn 

• I'm reminded strongly of my favorite quote from Naval Ravikant:

  If you're not 100 percent into it, somebody else who is 100 percent into it will outperform you. And they won't just outperform you by a little bit—they'll outperform you by a lot because now we're operating in the domain of ideas, compound interest really applies and leverage really applies.

MONOTASK

As a programmer, I tried to make sure that I was only ever working on one thing at a time. Even if I got stuck on that one thing—say I was blocked on waiting for a tech partner to give me API documentation—I’d let myself stay stuck instead of sliding off to work on something else.

In the short term, this made me less efficient, because I’d spend less time programming and more time staring vacantly at the ceiling. But if I stared vacantly for long enough, I’d eventually get mad enough to, e.g., reverse-engineer the partner’s API in a fit of rage. This resulted in me shipping my most important projects faster, hence getting faster compounding growth.

Only maybe 30% confident in this, but from personal experience I think having a secondary goal is personally useful, so I don't get bored or burn out on the primary one. (Actually it's kind of hard to first-principles reason about it so I'll just experiment this week).
