If I put a gun to your head and told you to do it, you would probably do it. You need to bruise your ego in order for you to grow. Simple as that.
The only reason these Anxiety programs work is because you have invested your money on the line and are more likely to do it. Same goes for bootcamps or one on one training. They only work because people don't want to waste their hard earned money. It's no coincidence that the people that torrent these programs don't handle their shit because they haven't put anything down on the line.
Don't waste your money, there is enough free content out there. I find this to be highly effective. Give a friend $100 and get him to promise you to not give it to you if you haven't done 4/5 approaches that very night.
Want to get into shape? Give a friend $1,000 and tell him/her to not give it to you back to you until you get into shape by a certain day. Get it? Create incentives till you sort our shit out.
We all have AA but we all choose how to deal with it in our own ways. 'You miss 100% of the shots you don't take'. Approach Anxiety is step 1. Making a move on a girl requires another form on anxiety but cross that bridge when you come to it.
Get it done, you live once,
you're going to die one day, remember that.
