I go to sleep at 9:30 and wake up at 5:30 every day. Sometimes I go crazy and stay up till 10, but that's rare. My bus leaves at 7 AM (40 minute commute), so that's plenty of time for coffee & breakfast & a shower before I have to head out the door. I get home from work at about 4:30 PM, plenty of time to cook dinner or do home stuff or go see friends or whatever before going to bed at 9.
My bus also leaves at 7 AM, with 40 minute commute, but unfortunately I have a very bad case of internet / youtube addiction, plus I'm basically a night person.
So I go to sleep around 12:30 AM each night (sometimes even after 1 AM), and I wake up at 5:50 AM.
That's not enough sleep at all.
I do sleep till very late during the weekend.
I've been doing this for 20 years now, and some day it's probably going to catch up on me.
