I'm editing the manuscript of my last client right now, as editing proved to me very painful because I'm such a perfectionist. I've been told I'm very good at editing, as good as a pro (which made my jaw drop, because I'm a total rookie), and I made money. I could continue making money editing, but it's not what I want to do. I want to write books and publish books and make money selling books, so I have deleted the editing page from my site, and I have only one client left (and after that zero).
