well personally I'd say you need to be passionate about something. I never like a girl who is boring, and has no interests. I mean, that could be... photography, surfing, soccer, or whatever. Guys also like girls who aren't bitchy, i.e. don't complain about their nails all the time, or how they look. Don't be too clingy but also don't play hard to get. Just be yourself, but a nicer, and sweeter version of yourself.
