Writers should be masters of their muses, not slaves. My muse works with me every day. If it resists, I know it's because I didn't spend enough time brainstorming or outlining a scene. The Artist's Way has sold probably a million and a half books by now. So I self-published the book, and of course discovered there was quite a market for it.
Writing is one of the most easy, pain-free, and happy ways to pass the time in all the arts.
For example, right now I am sitting in my rose garden and typing on my new computer. Each rose represents a story, so I'm never at a loss for what to write. I just look deep into the heart of the rose and read its story and write it down through typing, which I enjoy anyway. I simply relish the movement of my fingers on the keys. Sometimes, it is true, agony visits the head of a writer.
