Pretty much what Dragula said.
I fucking wish I went out and did all my approaches BEFORE reading up on shit. If you read all the material first, it makes your first approach a fucking big deal and adds so much pressure.
Because I did it wrong, I found myself in my first approach using inappropriate negs, trying too hard to force constant eye contact, and generally getting a worse response than I would if I'd walked over like a complete beginner with "Hey.. sooo... come here often?" lol. Worst part is that I'd approached girls before (not very many at all and rarely ever sober so it hardly counts), but that was my first "post PUA" approach so it was somehow a big deal lol.
Some things you can YouTube for now, though:

Something to do with mens hairstyles but I don't know which one or anything.
Infact, that's about it. They're just help with working on your look - some tips for colour matching, hair cuts for your head shape, grooming tips, better fitting clothes etc. A good haircut changes your fucking life
