Most Helpful Guy
Are you sure it's only an issue with girls? How well would you fare around, say, me and my friends if we chat with you?
Because that's the sweet spot as I see it: your ability to befriend and converse with strangers. I've never met a guy who was only good at picking up girls. If he was good, he'd usually be pretty good at befriending complete strangers as well (male or female, young or old).
It's a social skill in general as I see it. Dating a girl is one of the more challenging social things you can do. But it isn't that too much unlike befriending a stranger as I see it, and the nice thing with that is that you can practice all the time... if you're up for it. There are strangers all around.
