It would be nice if we could take a pill or get an injection and have all the cognitive strategies added to our brain at once. But that is not how the human brain works. The brain must learn new information -- and this takes time, because to really learn something well, a lot of repetition is involved. The more you do something, or the more you study something, the better you will become, and the more you will know about that thing.

There is no short-cut to learning (how to overcome social anxiety).

If we are discussing what will WORK in helping us overcome social anxiety, then there is no process other than learning what is rational and then acting on it (thus, CBT).
