1. Show sympathy and affection! If the girl you really enjoy being around is sad or hurt, give her a quick hug. Don't just say that you're sorry and you hope she feels better.Hold your left arm around her waist, right hand at the base of her neck or holding her head.
2. If you have braces, glasses and acne... don't be disheartened! Wear contacts, use some Proactive and voila. Girls put a lot of effort into their appearance, perhaps you should do the same.
3. Have good posture!
4. Don't act tough or try to be a thug. This doesn't attract girls.
5. Don't follow her around everywhere. It automatically gives you a reputation as a stalker, and it will freak her out!
6. If she just doesn't get that you like her (which most likely won't happen because girls are pretty good at detecting this kind of stuff!) drop hints!
7. Don't play games. Waiting a few days to call her , showing up a little late to things or anything like that is only proving you are unreliable, a fake and a loser. Likewise, don't tolerate it if she does any of these things to you!
8. Use correct grammar when texting her or talking to her. If you don't then she will think that you aren't very intelligent and that will turn certain girls off.
9. While it's important to connect to her friends, you must avoid coming off as a player. If a girl's friends do not approve of you, this will influence her opinion of you.
