Be careful not to appear over-confident, though.
It is always better to use your skills and qualities in a subtle way, as girls usually are put off by people who show off or display arrogance.
Relax and focus your attention on her instead of yourself.Don't spend too much time around her trying to make an impression.
Instead, spend lots of time, and then none for a while, then more again, and flirt while you are there. While you are gone, she is given a chance to think about you, which hopefully she will.
