I have a lot of potential, and so do you. It's a real problem, isn't it? It is for me.
I have no problem writing, but I always need to be writing more, and I need more readers as well. I was talking to an acquaintance, telling him how I admired his writing career, that I was not satisfied with my own. He advised me he wasn't too please with himself, that the writers he admired were far more accomplished. Assuming there may be someone at the top of this heap, that person is perhaps satisfied with himself.
The rest of us aren't.
