Welcome along.

Advice.
- First and foremost - have fun! if you're not enjoying it some of time, you've got the wrong approach to "PU" and maybe even life.
- Go out be social (talk and meet) with everyone. You'll meet girls (and guys) and gain much needed skills/experience in conversation, social dynamics etc. which will help you chat up girls but also helps at work & within social groups
- Don't forget to do other stuff. Constructive stuff that makes your life better like languages, music, arts, etc. It will improve you as a person and make you more interesting to girls but more importantly the former

Books & videos
- Mark Manson's Models - good read that helps you develop yourself.
- RSD blueprint decoded, if you can handle and cut through Tylers marketing I'm so great persona, it might give your balls the extra size they need.
- 30 days of Discipline. It's not PUA but I found it helpful to cut through some of the guff in my life.

Good luck
