tell me how to get girls to like me.
I can't really give any one person any specific advice to get girls, but here's a few general rules that I'd follow:
1: Dress well.
Believe it or not, girls like a man who's dressed well. Find a style (preppy works best nowadays) and stick to it. I suggest stores like American Eagle, Abercrombie & Fitch, Aeropastel.
2: Keep the nerd out of conversation.
Listen, I'm a semi-nerd too. But when talking to regular (non-nerd) girls, do not mention anything nerdy. (video games, computers, Poke-mans, etc.)
3: Be active.
Women also like a non-fat guy. Stay fit. I don't necessarily mean become a jock, but don't be afraid to eat a vegetable or go running every now and then. Obese = bad.
4: Be outgoing.
Don't be afraid of girls. They're people too. Don't be afraid to go up to a chick and say "Hey, how's it going?" Girls appreciate a face-to-face conversation over a text or MySpace message.
Those are just a few tips. One of the most important ones is to just be yourself.
