Some people are just not good for entrepreneurship, even if they do want it very hard. Desire alone is not enough. Success is a multiplication of factors, not a sum, and if you are bad at just one aspect you fail. I think you should find a companion or two and take a couple of shots on short-term projects with them. Not a big-deal-out-of-garage, just a project to check things out. The idea is to complement each other's drawbacks and form a team that is good at everything.
