This might sound a little shocking but I sleep at least 9 hours a night. Sleep is one of the obsessions of the biohacker. If I’m lucky I might be able to get to ten. It’s always a sign of me doing poorly if I am not sleeping a TON.
It’s usually the first sign I am not adequately reserving time to bring down my central nervous system into rest and digest. I’ll stay up till 11pm and then it’s a hop skip and a jump to only sleeping seven hours.
The best combination of effort and exertion for me is only adding in specific necessary stressors during the day and give ample time to recovery. Much of my work requires focus and information processing and synthesis. And that isn’t improved by overwork and exhaustion.
Nevertheless I am still carting around a lot of lessons from my childhood about the value of hard work. More is better. More hours is best. And this is a fine and noble thing if you do work intelligently with your goals in mind. Simple exertion is sometimes the best option. But not always.
