What would you do if ... ?

I am interested in this girl in my Statistic cl, used to think of asking her out but don't think it gonna work out( me: 18, no car, no job, just big heart lol and she: 24, starbuck manager, has car, house). So the thing is that I still want to keep in touch with her ( so that I will ask her out one day) but she is pretty busy. So I would appreciate if someone can suggest me a good idea in this situation. Thanks
