There's that old tale of the people chopping wood but one takes a bunch of breaks but chops way more wood than the other, and it turns out every time they took a break that they were sharpening their axe.

That's what sleep is to me, the most effective nootropic "sharpening the axe" you can do for your productivity. Unfortunately, that doesn't quantify easily like "hours of sleep" so it's harder to track.

I'm not a sleep scientist, but Fitbit's advanced sleep tracking has been a boon for me to collect data on how I'm sleeping.
