1. do not live in a house with majority girls. they go weird and herd-like, the reverse (group of men) does not happen. This is 3 years experience. Do not do it. You will regret it.
2. don't expect a fuck. ever. don't go into a dating scenario needing one. if you go into it that way my advice would be prepare to fail miserably.
3. an expensive haircut will help you get laid, put down the shitty wii game and go get one.
4. no matter how much you think the girl's a loser who you only want to use for sex, that girl thinks she's hot shit because you're attempting to get into her knickers anyway. you'll waste at least 3 months trying to get into them, so pick a fitter girl who is clearly hotter than you to waste 3 months. if you take any advice from this thread, take this one.
5. ditch the girl before you sleep with her if she's boring. and tell her she's boring, her friends will hear through the grapevine and your status will go up, even if they are slagging you off, suddenly you are unobtainable.
6. be nasty to losers, don't hang with them.
7. Imagine what Jason would do in your scenario. Don't do the opposite, do whatever you want, just bear in mind there's always a bigger loser.
