I don't think there's anything in your history which ensures that you are not going to be a success. Lots of successful people have lots of failures in their past and many are procrastinators. Lots of them question their own motivation and aren't totally confident about themselves.
I think the only thing that bothers me is that you don't seem to know why you want to do a startup. Prove something to other people? Yourself? Make money?
