I know too many people who struggle to stay up late at night, with the only reason being that it is “not time to sleep yet”. Flipping through re-runs on tv, surfing aimlessly on the web, or playing Flash games.
Sleeping late means waking up late. Or a nap or two during the day.
Why not sleep early, and wake up early? You can watch your re-runs and surf the internet in the morning. Or you can do anything you want. Chances are you will have more options at 8 am than at 1 am.
