All Christmas break, I've been sleeping at 4 A.M the next day. One of my friends said that it is a waste of time to sleep during the break as you can use that time doing something else. I've kept up with that ever since. On school days, it depends on how much homework I have. Procrastination puts me up to 2 A.M and if I do them on a timely manner, I can get to bed at 10 P.M.
