Very rarely, if ever, have I ever slept past 9 at the latest. I normally wake up between 6 and 8 in the morning. It's nice to have that fresh morning air, and have a nice pot of strong Joe in the morning, while everyone else is still in rem sleep until 9, 10, or even 11 or 12 (by that time, I joke to make sure that person is still breathing). I find early birds can get an early start on the day, and take on opportunity people who don't wake up until noon miss out on. Lots of entrepreneurs, like Elon Musk, are up by 7, no later. So, any other early birds catching the worm here?
I'm more of an early bird than a night owl, but I do sleep in on occasion. I do frequently wake at 3am and like to write and explore ideas during this time, it's the best time of day, no interruptions only my thoughts
I do all my best thinking in the morning. In college I would get up by three and do all of my homework. I get it done twice as quick at that time of day for some reason.
