Sleep. The most underrated productivity hack.

While remote working, we all have had numerous discussions around the importance of sleep, and read many articles about the benefit of sleep, but do we sleep well? I am a person who needs 8 hours of sleep every night to function. I always thought that was such a waste of time. I envied others who could just sleep for 5 hours and still be ok until I read the book 'Why we sleep'. (I might now agree with everything in the book. but that's beside the point) Are you consciously trying to sleep better? Or you already do? How many hours of sleep do you manage to get daily?
