reasons why not to chase girls:
If you run after a girl, she will, more than likely, run away from you. Just be patient and have some respect and attitude for yourself. Do not show that you are trying to chase other girls as well. Rather, make yourself so impressive that girls are after you and want to have your attention. Always try and leave the girl wanting more. Sure, go and talk to her, make her laugh, give her a complement but then return to your other friends. Chances are she will come back to you or she will try and make eye contact in order to talk some more.
