How many hours sleep do you need?
Last night I had 5 hours sleep. 2 am - 7am. Not a usual situation. Brought about by a client function at Darryn 's work. But it got me thinking. My optimum is 9 hours sleep - 10pm-7am. That rarely happens. But I do usually get 8 hours. When my kids were little I worked out that I could function if I got 7 hours a night (albeit broken sleep). When I had my scrapbooking business (Tuatara Tales) I usually had 6 hours sleep! Not good.
I've noticed that when I read profiles of high achievers they appear to need less sleep than we mere mortals. Many CEO's I've talked to only seem to need 4-5 hours sleep.
