How the way yo Study?

i can study in better way for me stayng in my livingroom, with no one near me, and with no noises, here i can do the best study, sometimes i try to study in the train, or in the university or in another room of my house, but i can't do so much. Here i can concentrate myself on the things i'm doing, drawing, whriting and understand my matematic analysis notes. It requires a lot of concentration and full charged brain.

I never like to study in my bed. I've heard it's not very good to do that since you associate your bed with sleeping. After you've studied, it may be hard to get to sleep.
I'm really bad about studying where there is a lot of noise, so I make sure I'm alone. The best place for me is at a table in the library. That way I can spread things out and see them all.
Studying at home is really difficult because it makes me SO unmotivated!
