Steven Pressfield, a dear friend, wrote a short manifesto, Do The Work. The title of the book actually answers so many questions. It is Do The Work, not Read About The Work, or Tell Your Cat About The Work, or Think About The Work.
I asked Mr. Steve only three questions, following the example of my typist who has interviewed Steven Pressfield before about his books, The War of Art, and Turning Pro. Both excellent books.
