My friend says he just can't approach though he wants to. Froze up the one time he did.

So my friend REALLY wants to learn to talk to people, not even girls. I told him everything I possibly could and even made him read the guides on the sidebar. He's a very good looking guy, rich, tall, top student, but he lacks confidence severely. The one time he approached a girl he just froze and I had to pull him away.

Does he have social anxiety disorder? He says he just can't do it though he convinced his brain to. He just freezes. What can I do to help him? He lacks confidence to even say hello to random people. Does he need liquid confidence to open his mind?

Help much appreciated.
