Don't pretend to be someone who you are not. And be funny and just show that you care? It depends on the girl you like
Be me =P I'm kidding (before some **** sees this and starts calling me arrogant).<br />
Just be confident, like ultra confident, self assured and don't give a **** what other people think of you. That's a start, but you also need to be assertive and in control of every situation you are in. Be a leader.<br />
That works for me.
Be clean, dress nice, smile. Have a job. Treat them with respect.
Have lots of money or be incredibly good-looking. They like to CLAIM that they're less shallow than men...
Depends on the girl you'd like to like you ;) But just be cool. Laid back and funny. Don't do mean thing but still avoid being to nerdy :)
