I don't have a job right now, I shifted my sleeping scheduled a few hours back so that I would have 5 hours before school and 3 hours after school, so that school is now in the direct center of my daily schedule. I also have friends in two completely opposite timezones and this allows me to talk to them both without staying up late/getting up early.
It's worked out for me in numerous ways and I feel much more energized throughout the school day. I'm not exactly much of a social butterfly or a party goer so I have no real reason to be up past 7-8PM anyway.
How different does it feel then going to bed at like 11PM?
OT: In the summer, around 1AM. During the fall, winter, and spring (school days), around 10PM.
