How can I become a very studious person?

I am at school in my 13th year. Starting to get very bored of the whole school routine. My dream is to become a Chinese teacher. Next year I hope to attend university. Does anyone have any tips on how to change from a lazy person who likes to procrastinate to a very motivated student? I know I have the intelligence it is the motivation I am lacking.. any ideas of how i can improve my motivation or ways in which i can become studious?
