Just the fact that you're doing it would imply otherwise... I believe most people choose to do things they are good at, not the other way around. Whether for a career or a hobby, the potential rewards are so much greater, not to mention the notion of fulfilling your calling.

I think writing is like acting, sports, etc. -- it takes some luck to break into it. You just have to keep at it and not be discouraged... you never know when the time will come.
