Perhaps it's just my low self esteem, but I doubt my writing every single day. I cringe, thinking of some of the things I've done to move the plot along. I feel like my writing is shallow, boring, and poorly constructed, but I keep writing, chasing the story as I see it in my mind's eye. Too often, I feel like I'm just not good enough to tell it. I know a lot of writers - and artists of all varieties - sometimes struggle with nagging self doubt. How do you believe in your writing? What keeps you going?
