when it comes down to it, every girl is different so there is no surefire way to win her heart, just be yourself! even if you're shy you'll have good conversation with the right girl
work first, games second
respect, don't talk shit and you won't get your ass beat
don't tell some one that they should come watch a youtube clip that is nine minutes long while you stare at them waiting for them to laugh - (so many of my douchebag floormates do this)
dont trash what other people enjoy
don't take a call in a library/classroom, if you need to take it step out
shut the fuck up sometimes, you don't always need to be talking
don't sing along with an entire song if no one else is singing, you are ruining it for everyone
dont be offended when some one says they dont know the words to your favourite beatle's song - not everyone listens to classic rock
like who you are, or change so that you do
if you live with other people listen to your music with headphones
smile!

no one will talk to you if you are always frowning
