Another anecdote: I've kept meticulous data on my own productivity for years, which has allowed me to run self-tests on the effects of sleep, exercise, substances, etc.

One thing I've consistently found is that the harder and longer I work, the more I get done -- without bound, and without burnout rebounds. It's just all shockingly linear.

It doesn't feel linear: the difference between working 12 hours versus 14 hours in 1 day can be excruciating. But when I step back and look at the graph over longer time spans, the "time spent" vs "how much I got done" relationship appears to be pretty consistent.

TLDR: I've personally convinced myself that "hustle culture" works for me.
