When I’m highly motivated and want to accomplish huge technical work I will shift to sleeping 2-3 hours, working 6, then sleeping 2-3 hours, I will keep doing that for as long as 4 days straight and do nothing but work, sleep, eat. I don’t tell many people this as they think you are crazy, but my family knows, and they think I have a mental health problem. I don’t at all. I function completely normally and fully regulated in all ways. I just really really want to accomplish something asap.
