What is prevention you?

I have two weak point. My first weak point is sleeping. I have much sleeping, so I am tried every day. especially, when I start to study, sleeping is coming to me very fast. In spite of oneself, I fall in sleeping. I need to study much more than other students. but I spend the time in sleeping. for wake from sleep, I try to drink a coffee or expose to the air. My second weak point is patience. I need patience, because I am boring easily everything. So when study, I study for 50 minutes, and I have break time for 10 minutes.
