How do you show her how awesome you are?

I like this girl we are both freshmen in college. She has only had two boyfriends in her life, the first one she broke up with cuz she liked someone else. We get along amazingly, and she said she likes me and I like her, but at the moment her schedule is like wake up to go to sleep packed tight, and so is mine, but I still want to date her. Her biggest issue is that shes indecisive becuz of the first relationship, she is afriad that if she started dating anyone, becuz she is naturally flirtatious she might start to like somebody else while she was already dating someone. Is there anyway I can make a huge impact in her world to show her like how great we could be and stuff? or any other suggestions?
