L.A is right. I cant even beleive what I use to be like in school. I can actually say I am NOT proud of my old self. But at least your on the right track man.
It sounds to me that your still in school for starters. Thats one tricky situation. But it can be handled. First thing I would suggest is hang around the friends that respect you the most. Do not let your friends disrespect you in front of no one. If you have to pull them aside, tell them to never do whatever it is that they do again(lowering your social value). If there you friends, they wont do it again. Another thing, I dont think it would be wise to share with them what you are trying to do with <a href="
">PUA Forum</a>. You could be giving them another excuse to be a pain in you ass and your just gonna end up

and loose your cool.
I strongly suggest (and this is just a suggestion) to get the PUA Home Study Kit. This is not free and you will have to drop a few bucks. But it contains some exelent exercises you should do, and do not forget to fill out the PUA diary. This will help you analyze every situation after it occured so you can be more prepared and handle it better if that specific situation happens again.
Start off doing ALL the fieldworks. these are just examples of things you can do to loosen up a bit around people.
1. Go out one day and smile to 10 girls at school
2. Next time, smile and say hi or hey to 10 girls.
3. Next time, try opening up a single set (one girl alone), just open up, say hey whats goin on, dont you take (math,science) or whatver you want. You dont have to stay there long just open and leave elegantly. let her know that you will see her around later.
Oh yeah and stay clear from bullies/bully's or Jocks. Untill you can handle it. I also strongly recomend reading the (Alpha Male program for dating and relationships) this will give you a better understanding of what is an ALPHA MALES ROLE in society and how you can become one.
Dont forget to give me some props when done reading this. Just look to your left and press the plus sign.
