I'm in my 20s and I have a terrible habit of biting my nails. I am terribly self conscious about my personal looks because of it. I cant help but think of myself siting at a bar and hitting it off with a girl just to have her look down at my hands and see the gnawed off ends of my fingers.

I was just wondering if anyone else has this problem and if it has personally hindered your performance at picking up women, or even just a way that you have overcome it.

Also if anyone else has had this problem how did you stop biting your nails? It's a disgusting habit that even I am ashamed of but unfortunately a very hard habit to break, and my previous attempts at quitting have been terrible failures.
