I don't think I'm a jerk or a badass. I'm pretty quiet too and can sometimes find myself uncomfortable in certain everyday social situations. I'm no Brad Pitt either. However I do have confidence, I do accept my faults and I've learned not to pick holes in myself because of them. It's amazing how easy it is to just accept the things that make you the person you are and realise that it really isn't all that bad. Doesn't mean I don't try and change those things still, just that while they're there I don't beat myself up about it.

As soon as you realise you're really not so bad, it doesn't matter if you're quiet, shy, mild mannered. Because when a girl talks to you she'll see the natural confidence of someone who is happy with themself. From then on it gets easier and easier. Good luck!
