I'm thinking on disregarding any kind of social life apart from my time at school and coming up with the most effective sleep routine of all. Living the life at night and morning, sleeping around afternoon and evenings.
School starts at 8:15 am and ends at 3:05 pm. If I go to bed around 4 pm and wake up around midnight, it would work. I get "activated" around my 9th and 10th hours of the awake day so if I were to switch to this odd routine, my most active and fresh minded hours would go to school, I'd enjoy my favorite time of the day (night and early morning).
The only problem is that the world doesn't work that way. I have a great chance to give it a try this week. Not the healthiest one (it's built on passing the sleep of night) but the most effective, for me.
