Cool lifestyle. Done some of that kind myself. >I noticed when I focus for 3-4 hours on some tough problem, then interrupt and do something completely unrelated or sleep, I get surprisingly many ideas quickly leading me to a solution. If I just sit in front of a monitor, it might take a week to solve the same. Weird, but works for me. I don't think it's weird. There are many anecdotes of that sort of thing being helpful with work, particularly mental work involving problem-solving. E.g. >"and do something completely unrelated or sleep" The German chemist Kekulé discovering the structure of benzene in a dream - read about it in school chemistry class: https://en.wikipedia.org/wiki/August_Kekul%C3%A9#The_ouroboros_dream https://en.wikipedia.org/wiki/August_Kekul%C3%A9#The_ourobor...
