>>5961761>less than usual sleeping time are far enough to build up multiple skillsI think two important things to note in this vein are that if you get high-quality sleep you only need a few hours a night, and that our natural state is a diphasic sleep schedule but industrialisation cucked us all (it cucked night owls, people naturally predisposed to going to sleep and waking up a few hours later than everyone else as a group adaptation to watch for predators, even more though).
Note my experiences in this vein are corroborated by literally all of my friends that have experimented similarly to me as well as many people I've talked to on 4chan about it over the years, but conflict with the typical lines from "sleep scientists" (who are usually just psychiatrists who happen to be talking about sleep, but the media likes to call them sleep scientists to make it sound like they've dedicated their entire lives to empirically studying sleep) and the CDC. However, I've found that contrary to the CDC line (that everyone needs at least 7 hours a night and people who get a lot of exercise need even more in proportion to their physical activity), the more I exert myself, physically OR mentally, the higher-quality my sleep becomes, and the FEWER hours I need. When I was talking 15+ miles a day (up to 30) every single day without a single skip day (even when I injured an ankle sprinting downhill), I was also sleeping about three hours a night and waking up feeling full of energy. When I get a more healthy (ie less excessive) amount of exercise (including mental exercise) I usually sleep about 4 hours a night. Meanwhile I've had colleagues sleeping for a third of their life and operating at half their potential because they were dog-tired the other two-thirds.
It's no wonder so many people think it's only possible to master one, maybe two skills in your life, when they're missing out on two-thirds of their time-potential because of bad sleep habits.
