Writing Advice: Write Only for Yourself

Ray Bradbury said "Write only for yourself" This is excellent advice! At times I've gotten stuck in my writing, and after thinking about the cause, I usually find that I'm attempting to write for the wrong reason. For the past couple years, I've been writing short stories in hopes of getting published in one of the SFWA (Science Fiction and Fantasy Writers Association) recognized magazines so I can become a member of SFWA. Sometimes I catch myself trying to write not from my heart, but with an end goal in mind, publication. This means I'm on step 2, but thinking about step 12.
