His cockiness is partly due to his Jewish background and his lead role in a highly popular rock band. It's easy to be confident when everyone wants your autograph and all your character flaws are brushed off as irrelevant compared to your skill.
At the end of the day all that matters is results. I care about results. I don't think anyone is going to argue the fact that if you take two men of equal looks, the one who is confident (hence approaches more) is going to fuck a lot more good looking women than the one who isn't. This is indisputable. You can either play the numbers game or you can sit in the corner and wait for women to come to you..
I used to be that guy...always waited for girls to talk to me and play it safe because I couldn't live with the thought of being rejected.
I got over it...and went from on average, bringing back a hot girl 1 out of 2 weekends nights to have 5 to chose from every weekend.
Do you think my friends remember those other chicks that rejected me? nope
but they sure as shit remember the ones I brought back with me.
