I'm not an expert either but well,I think I've learned tht waiting for the right moment is not the thing to do.stop bullshitting yourself into thinking you can wait around and show some balls.she's more likely to be impressed by a gu who has the confidence to walk over and start talking to her.It doesnt matter if your really feel like your gonna collapse .you can do that later when its over and done with.just act and fake everything til your through it.like poker ,but dont be completetly emotionless
