Look her in the eye, say hi to her and smile. Get to know her; maybe she will want to go out with you. Compliment, flatter and praise her. Exercise, watch your diet, and make sure you are getting enough rest every night. If she is not interested, move on to the one who reacts favorably to you, but you still must take that chance to find out if she wants to get to know you better. Take a deep breath, have courage; you can do it.
