Hi and welcome MOOT!
I'm not even close to be a PUA, but I'm off to a good start and I had the same things. I had my prom 2 weeks ago, and I was very worried about it as I didn't have a promdate. I made a whole 'game plan' to get a date but I found out that if you're going to make such a big deal about it you will fail a lot faster. I went dateless to my prom but I had such a great time. Now I can't believe I was thinking about not going

.
So just go out and have fun with girls, it isn't homework. Try to set goals that are not impossible to accomplish. And I found out that keep a journal/diary about your succes with women is very smart to do.
Good luck!
