As a new author, I am learning something new all the time. In fact, in life the minute you stop learning is the minute you stop growing (my opinion). I have tried to read as much as I can about the market and when that doesn't work, I try to ask the authors who have been in the business a lot longer.
I am a very private person. And I think I have mentioned a time or two before that no one ever read any of my works until I started submitting my books to publishers. So having someone I know critique my work is very difficult for me, I haven't quite mastered that thick skin yet.
So anyway, I've been wondering: If we are our own worst critics, why bother with crit groups and/or partners? Are they truly necessary to become the best writer one can be? Is that the only way to be truly successful as an author?
