This is a thing floating around, I think it's far more correct than the default aphorism, and I thought it could use some signal-boosting.

But I don't think it's only about everyone starting as a beginner. That's true and important to keep in mind.

And it's not just about how perfectionism can stop you from delivering on important things, and how the urge to perfectionism can be costly and damaging. That's also true and important!

But it's more fundamentally, to me, speaking to the planning fallacy, about how people think things can go well, and any decently important plan will definitely go awry. If you want to know if something is worth the investment, imagine the outcome when you do something poorly. Is that still good enough to justify the returns?

If you're completely sure you can execute with extremely high quality, without fail, and without delay, it's possible you're undershooting the amount of ambition you ought to have. Try something harder. The simple things, well, they aren't worth spending your life on. Not all of your life, at least.
