Well try to really get to know these girls as friends first. If you get to know them well enough, underneath they might be just the person you are looking for.

"First off, girls that want to be with eccentric/super-capable people like myself are still relatively rare."

Sounds kinda cocky there haha. Don't get too full of yourself!

But yes, its difficult, I'm not picky, but I've only ever liked two girls in my life. It wasn't as if I thought "oh this one is too ugly, or fat or dumb, so I'm not interested", one was cute, the other was pretty, but I liked them because they were very different from the "average" girl and were kinda perky and positive (I'm silly but negative). They made me smile on the inside, which never really happens so I was attracted to them. But I gave them up like a fool.

Go search and don't give them up when you find the right one! You lose a bit of yourself if you decide to give up the very few you actually cared for.

Exactly how well do you know these girls?

It wouldn't be any fun if the second you meet someone you know they are perfect for you. Find one you kinda like and then go on a date. You may like her more when she's one on one and not surrounded by your other admirers oogling your athletic body haha single one out and ask her on a date.

Otherwise you'll just have to wait, because therre's really no way to get girls you only like to come your way so you just have to go out and find them!
