This is just noise, and I've proven that to myself over the years, but it still affects me every...single...time.
Two questions for HN:
1. What are your favorite methods of overcoming this doubt?
2. What books (or other resources) would you consider helpful in this regard?
Thanks very much in advance.
Edit: All in all, I think it has come down to me being honest with myself about what I want to learn and why. This helps me to have realistic expectations about learning some new things.
