pjgat09,
I just put a post up on my blog so I'm going to pimp that here:
How to always know what to say and do. Bold enough statement, I understand, but it fits in if you adopt an inside-out approach to live.
cylon's advice is spot on IMO. If you're focused on the other person it makes conversing a lot easier.
This post has a lot of good advice on vibing.
Remember Steve is a fan of ready, fire, aim approach to learning, meaning get your feet wet by starting to talk. Talk, fall down, talk some more. You seem to want to go from being very bad at conversing to being the ultimate socialite. Your brain is probably rejecting this idea because it seems impossible to do.
Also, since I'm such a fan of affirmations, saying "conversing is pretty easy for me" and "i'm able to carry on conversations" will help. If you belief you're a good conversationalist and you vibe well it will make it easier.
Lots of love,
Colm
