First - build a sexy body - people like to fuck.
Second - acquire currency - people like to eat, drink.
Third - learn to communicate - people like to converse.

Then you go out.

If you're a man: hide your interests in Star Trek, socionics, gaming and all kinds of non-concrete-world mumbo jumbo like that. This is not instinctual enough for girls, it's too mental, gets them too far away from sexuality and emotions.

If you're a woman: tame your bitchiness and get real about the world, guys aren't turned on by your career achievements, but things like genuine femininity, sexiness however much you can show, and basic respect to a guy can go a long way.
