Do what I do. Carry on with your life and don't worry about it. The minute you stop actively looking, girls seem to flock to you. Seriously. Try it. Added bonus is that if it doesn't work, you'll have been focussing on more important matters and, in theory, achieved other personal goals.
And my top tip when it comes to treating the many lovely ladies of this world? Just treat them like you would anyone else. One girl in my old school, Lauren, hottest girl in the school by a LONG way. Every morning the idiots would be hitting on her with their latest lines, all of which failed. I'd walk in, say hi, ask her how her day was going, show no interest in getting in to her pants whatsoever, she spent most of her free time with me. Eventually led to a rather fiery relationship. Try it.
