Oh man. You're falling prey to so many assumptions and stereotypes here it will be hard to address them all.

You're trying to change who you are so you can pick up chicks? Not going to work. Not only will the girls see right through you, but trying to be someone you're not is stupid and ultimately hurtful.

And who said being a "bad boy" is the ultimate turn-on? There are lots of different types of girls out there. Find a girl who has the same interests you do. For example if you're into ballroom dance, go take dance lessons and strike up conversations with the women there. If you're into comics, go to conventions and events at local stores to meet like-minded girls.

Ultimately my advice is you will be successful if you are confident in who you ARE. Being outed as a poser is far worse than any dating dry spell.

Yep. And besides, not everyone can be a bad boy. Especially not you... because in my mind the reason women like the bad boy is because he doesn't care. He isn't trying to impress them, he is just doing his natural boy thing. He might be passionate about something, or he might be angry about something, but he surely isn't sitting around his house eating microwave dinners, wondering how he can appeal to more females.

So you already lose. But my advice is to be selfish, and do exactly what you want to do, regardless of whether anyone is watching.

the best way to atract girls will always be to be yourself. you'll find the one someday.

You need a smart girl. I didn't have to edit your request at all, and that's apparently a very rare thing. Just stop caring, once girls get the vibe that you're not looking, they'll come after you.

Lotus is right.

Maybe, in order to just feel a bit more confident, you should take some time to think about the things that you feel are your strengths. Are there things you want to do, or ways that you would express yourself, but are hesitant to act on? Do the things that come naturally to you, push your boundaries and draw attention (in a way that doesn't feel contrived) to the things you love about yourself. Confidence and self-knowledge are inherently attractive, as long as they're sincere.
