Does an intense fear of failure - due to lack of skills - cause one
to give up and not take appropriate actions in social situations?

One thing I know for sure, if my social skills were better
I wouldn't be so afraid to begin conversations with strangers!
Why? Because if I knew how, I'd do it.
And then I wouldn't be labelled as being a shy person.

I know I can only get those skills by trying. But I'm afraid to try
and fail. How do I know if I'm shy of just afraid of failure? Or are
they both the same?
