Actually, it works. And one other thing I've to share: learn to say no.
It was incredibly difficult for me to say no to anything my first crush wanted to do, or when she asked for help. I'd be her little puppy, doing whatever she beckons or even slightly hints at. I think it comes with the lack of experience.
But after that, I learned to say no, and I pushed myself to gain lots of courage. I'm not a jerk, but neither am I being made subservient either, and girls DIG that.
