how to become cool?

well it's been a long time..
last weekend i went out for a drink, since it's my vacation and i've been away from the city for about a week. i just missed it sooo much. i've been so tired recently and the decision to go out took me quite some time, should i or shouldn't i? at last i thought well why not? so i hit it to my favaorite lounge. i sat there for a while drinking my coctail, some men came to chat with me, but they were all old and from some weird countries, wanted me to come party with them later, but i didn't have that plan, at least not with that old guys.
but i did notice not far away from me in the corner a pretty woman. don't get me wrong, i'm all straight, but i appreciate when woman take care of themselves and i'm not shy giving beautiful people compliments, even when they are female. so she was there also alone and she smiled to everyone, chatted to everyone who wanted to chat with her. and i was tired from my 'company', so i thought 'what the hell, i'm bored, why not see who that woman is'. so i started chatting with her and you know that moment, when you recognize that yes, there a person who is as beautiful inside as she is from the outside. we had fun, laughing and talking.
anyway going home that evening i became slightly envious, i wanted to be like her, i wanted to be cool. it was the very first time i met a person who i wanted to be. so how to become cool? it's not like i don't smile to people.. okay, maybe i'm a little too impatient.. i would love to know what made all people, including me, want to have her attention?
