My big secret was: pretending to be a robot.

I call this "aspy game". I used it to great effect in high school, to the extent of feeling that even if I'd never gotten laid after high school I'd still feel like I'd aced natural selection's test. Being naturally narcissistic probably helped. So I guess my secrets to social success, especially with hot chicks, were: dressing well, exercising, befriending a few of the highest status people, and aspy game. (Befriending the highest status people was surprisingly easy. But maybe that was just anthropic selection.)
