Plan what you'll say before approaching someone you're interested in. Winging it leads to freezing up and awkwardness. Having something ready keeps you relaxed and makes the conversation actually work.
Chapters
This tip is to have something to say long before you're actually talking to her. Nothing is more painful than finally getting up the courage to talk to someone and then realizing you have no idea what to say. And then you just freeze up, and then you start sweating, and then she starts sweating, and it's just, it's an awful, awful experience that should be avoided at all costs. So save yourself from the embarrassment and the rejection by knowing beforehand what you're going to say. This really helps you relax and makes the entire situation fun and exciting instead of awkward.
