Fears and non-fears

Afraid of making a mistake, I avoid doing something, while wondering if it's a mistake to avoid doing it. 

Although I'm worried that doing it may not be a mistake, still I avoid doing it, because what if others think doing it would be a mistake?

And though it would be a useful fear to have, I don't wonder if others would think avoiding it is the mistake.

I wonder why I don't wonder this.
