Being a writer is kind of like being on a crazy carnival ride. There some beautiful and exhilarating moments: finishing your first novel, scenes that seem to write themselves, characters who write their dialogue for you. Hopefully the beautiful moments will far outweigh everything else. A good review, a positive critique, or a friend who tells you they love your novel - those are the things that will fuel you and keep you going.
Then there are the terrifying, yet exciting moments: going to your first critique group, giving your first novel to a beta reader, sending a query to the agent of your dreams.
Finally, there are the moments when you want to stop the ride and jump off: getting a harsh critique or a bad review, getting rejection letters from agents and editors, getting rejection letters (yes, I said it twice), or the days when every word you write is a struggle. But these painful moments help me remember how much I love to write. And these painful moments sometimes produce the most growth.
So, even when I want to stop the ride, I know I can't. This is who I am and it's what I love to do. Besides, I have too many characters banging around in my head who want their stories told. I think they would eventually drive me crazy if I didn't write for them.
