How to come off as a great guy and would be boyfriend material?

Alright. I like a girl but she's not interested most likely. But that's not the point. I want to impress or be someone somebody could date. I have abs (not rly important), I like to cook, play videogames, skateboard, and draw. I am kinda protective when it comes to friends. I guess I'm ok looking and I good hygene. I'm going into highschool and I just don't want to be alone.
