I don't consider myself a writer, although I've had a couple articles published on some of my favorite topics. Living with a writer has taught me just how daunting certain creative career choices can be.
Writing has got to be one of the most difficult professions to make money at - right up there with acting and music. Everyone is groping for their "15 minutes" in the spotlight. Some make it due to sheer persistence while others get lucky breaks, or just make the right connections. It doesn't necessarily mean these are the most talented or very best in their class. Did you ever read a book by a major publisher that was just crap? I'm sure everyone has paid good money to see a movie with big name stars that was so poorly executed it was an embarrassment to be seen in the theater. I've often seen better acting and production in unknown, small-town stage plays.
I certainly don't know much about acting, but I have had the opportunity to observe a number of writers with a common affliction come together in what has become a life-changing experience. Ordinary folks became published authors, in a relatively short period of time, even with little or no formal training.
For whatever reasons, an astonishing number of writers suffer writer's block, or a "fear of writing." In finding her own way to a path of healing, Milli Thornton developed an inspiring and enjoyable way to help other writers overcome writer's block.
I have tried her "Fertile Material" writing exercises myself and was amazed at what I could produce in half an hour. She has even written and self-published a book on the subject, Fear of Writing. I give it my highest recommendation.
Good Luck,
