baroness thatcher was known for sleeping only 4 hours a day. lots of other entrepreneurs and politicians also get by on little sleep. e.g. elon musk.
how do they do it?
some people say it's a gene where other people say baroness thatcher trained herself to get by on little sleep.
i want to emulate them so i can get more things done in the day.
I noticed that if I sleep long the night before (9hrs) and I stay awake for a short duration of time (13/14hrs) I find it almost impossible to get out of bed with less than 7 hours sleep.
But if I stay awake longer (21hrs instead of 13/14hrs) I find it very easy to get out of bed on 5 hours sleep. In fact, I feel as refreshed as I would on 10 hours of sleep.
Baroness Thatcher (or Mrs Thatcher as she was at the time) probably caused a lot of people to lose sleep worrying about their future given the mass unemployment her policies created.
