This isn’t actually an argument against sleep. Sleep is crucial. You can’t function without it.
This is an argument in favor of finding the thing that keeps you up at night.
When you find that thing — the problem you need to solve, the product you need to sketch, the poem you need to write — you won’t be able to sleep until it’s done.
And that’s worth it.
Let yourself sleep when you need to. If it’s worth staying up for, you’ll know.
