I never appreciated 'positive heroes' in literature. They are almost always cliches copies of copies until the model is exhausted. I prefer perplexity doubt uncertainty not just because it provides a more 'productive' literary raw material but because that is the way we humans really are.
I went to a motivational training course once a course of self-discovery and I found out after a week that my fear - it was not a fear of not being accepted - was a very violent fear of failure.
