Someone will always be further along the path to success, whatever that means. It doesn't matter what stage of writing you are in, if you compare yourself, you are wasting energy you need to write. Just keep plugging away at your projects. Get them finished. I was at the Willamette Writers conference this past weekend. If I compare myself to the success stories there, I could get very depressed. So I don't. I congratulate them and keep writing, learning and stretching.
I'm a serious writer, meaning I have a regular daily writing habit, and I'm interested in sharing my work through publication. My favorite literary form is the novel. I write to entertain myself and my readers.
