Pressfield encourages his readers to use whatever one can to stay focused on creating and doing their work. He shares how he reviews his dreams and experiences to see what he could learn from them especially with how resistance shows up his life. He also suggests to be open to muses, angels or other creative energy. He defines the ego and self, and gives an overview of how these are in constant conflict with each other. For example, the ego likes things the way they are, where the self wants to evolve. He further discusses the differences between the ego and the self to help the reader move beyond the ego.
I encourage you to buy a copy of The War of Art for a better understanding of your own creative process. Whether you're a master artist or beginning artist, this is an excellent book.
