How do I get him to like me?

Okay so I like this guy and have liked him for a while now. We text sometimes and see eachother on the weekend but we rarely talk. He is a jaar older than me and goes to a different school. Most of the guys at my school say that I'm pretty but im short...does that have to do with anything? Can any of u guys help me door telling me what to do for him to like me? If u need anymore details just ask and I'll answer. Thanks alot :)
