Ask her to go out with mates, as a friend and always make sure you return her smiles and hellos :) Try going somewhere fun like the zoo or to a movie or a themed restaurant. Tell her when she looks nice, or you like the way she's done her hair if she changes it for example.

Confidence is key - it's very attractive in a guy - and it doesn't matter how you look if she's a good person!
