14 is the prime age to start focusing on your education. Bah, whatever. Waste precious time by focusing on "hot" girls that you'll break up with 2 weeks later. Don't go running to anyone when you're unemployed with no college degree.
Be honest so she would know she can trust you and knows you wouldn't lie to her she wouldn't mind going out with you! making her laugh girls like a guy that can make her laugh.. Just be yourself you do not have to change anything for someone to like you if they don't then just move on :D
Get a girl to like you? BE NICE! BE A GENTLEMAN! BE CHARMING! Girls like boys who will open the door for them, hold their things, etc. Are you interested in a girl? Be nice to her, compliment her, and try to find things you have in common. When you feel comfortable enough with her, and you want to make your move, tell what you like about her. Don't be afraid! We're harmless. If you've been sweet to her, she probably will like you back. Even if it takes her a while to admit it or realize it. Being a 14 year old girl myself, if a boy did that to me, I know for a fact that I would like them back.
I always liked guys who are into more in-depth things; stuff that takes real thinking and contemplation. Not just video games and sports (not that those things are bad, it just seems like sometimes they're all guys care about.)
