for me i went with the attitude go out and have a good time perhaps think about settling down with a good women in your 30's.... am 34 and am getting married in October! No regrets and some awesome memories! LMAO
ive done all the mind playing games, and acting cool and shit but unless your prepared to keep up the charade it soon gets boring and frustrating... be yourself - definately dont be a pussy, but dont be a dick about either!
Get an accent and use it - it works wonders!
