So you want to be a writer. My advice is to start writing on a subject you know about! What could be easier than writing about something that is already in your head? Your a decorator? write a 'How to' book on decorating. You would be amazed how many people can't paint a door. Your a Carpenter? write a book with some 'Projects' in it for the hobbyist. Write about what you know and the rest will follow.
