Let me lay this out... from somebody who used to have alot of trouble with this kind of thing.

Be confident, be cool, but do not under any circumstances, try to be something your not. Be yourself. If a girl doesnt like you she doesnt like you, keep moving, its nothing to cry about. Theres millions of fish in the see, some of them are bound to be great for you, but your never going to catch one if your too chicken to fish.

And dont worry about a girl being "out of our league", you may be a little leaguer in yankee stadium, but they respect that you have the balls to swing.
