Same here. I surfed the internet and played computer games until 1 or 2 AM every night, and then spent a lot of time in junior high and high school nodding out in class.
I really learned almost nothing, which isn't the fault of my teachers or anyone else. I would have been better off in a radically less structured educational environment, something as simple as being put in a room alone with some books and an offline computer for 4 hours a day, with long breaks in between to exercise and socialize.
Likewise for me. Upon starting college (and getting rid of morning classes), I found I slept better (and longer), had less migraines, and retained information better with less effort.
