I've spent the two or so months reading about different pick-up tactics and 'game' online. I'm ready to put it into something of a more in-depth action pretty soon.

One thing I'm worried about it approach anxiety in future approaches. I tried a couple of cold approaches recently on my university campus as a means of warming up to the pick-up world, which took a bit to get used too, but I managed to get over it moderately fast once I got the conversation going (which only worked about half the time when I attempted it; when I wasn't getting one or two word replies from the girls).

Overall, any general advice for a beginner?
