Fear of not being good enough, of screwing up, of never being able to make people proud of me. Some perfectionism in there too, I guess there’d have to be. Concern that I can’t trust in anyone or anything because if I do, it, or they, will disappear.
Fun!
Nope. That would go against my nature of course. Being Epimetheus and not my brother Prometheus, I would have to say thinking something through before doing it(or allowing it) would not be possible. 
Doubt. It is the mother of all my other fears, and something I battle every day. My self-doubts could fill a book, and not a thin one either, I’m talking War and Peace.
Arrogance. I am more arrogant than reality will support. I never doubt. The combination of the two can make for a very overly inflated sense of self worth. I usually have to be close to the best at everything I do or I give up. I also can convince myself of pretty stupid things and then hold onto them through fear.
I’m not driven by demons. They stop me from doing what I want so I guess they drive me into a cul-de-sac and stop there.
Some would call my demon self-doubt but I call him Hoke.
Death… Death is stalking me!
Fear of obesity.
