I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. - Dune, Frank Herbert
I think fear and perhaps even fear of fear is a major part of the problem. Having realized that I am thinking about what I need to do to get into solution mode and stay there.
