Haha yeah I am going through the a different process right now.
1. Do it until your happy with who you are! Everyone that learns about PUA and puts effort in this pick up the alpha traits takes time but you can be anyone you want to! You can be sociable, funny, and cool you just have to study those people and see what makes them that way! Join clubs that you like or just try some out so you can go out your comfort zone! I did this and it works! Even if you don't stay just go for the eff of it. Join a sport too. Something your passionate about. Write down everything you love and love doing and study them more deeply so you can talk abou it with people and they get drowned by it. This is super effective! This is the reason you should study everything girls like: shopping, fashion, tv shows, celebreties, and school related stuff, so you can connect with them and have a solid friendship and from there you can move on to anything if you get good at game!
2. I did and am exactly doing what I said up there^ . It has helped me so thats why I'm letting you know! If someone ignores you when you talk to them just remember that the feeling you'll get from this will make you grow stronger (and this is soooo true)

!
3. I have no idea what you meant to say lol but all i can say is never be rude. To anyone! You goal should be to outgoing and bring into your world everyone except if their been little bitches you know? You will find out that as you become popular you will drag even guys into you life because they figure your cool and you can be the key for them to get a girl you get me?
Just list the top things that you like and the top things that girls like and find out about it! Find the most recent stuff, where to shop, what movies are coming out, what theaters are awesome, which celebrity is hot and shit like that. Girls like when they can discuss this shit with you but only do so if you just want to be friend or else it will be awkward!
Anyway ask me any thing else or PM if you get stuck or need motivation. I will try to help you from the extend of what i have done and know.
