Steven Pressfield sets the stage in his book, The War of Art, for understanding the power behind the creative battles. In this first book of 3, he identifies the enemy within every creative being as resistance. Resistance comes in many forms. While he identifies the many paths resistance takes, he warns his reader of the insidiousness resistance takes to get one to give up, to fail, to quit. All of these are distractions one uses to not do their work. He begins with the type of activities resistance usually rares its ugly head -- no matter whether if it's caring for one's health, their education, or launching a new business. Resistance, he suggests, is fed by ones unconquered fears. As the author suggests, we have two lives. The one we live and the unlived one. What stands in the middle is many varieties of ways resistance presents itself. This book is a quick, yet to the point, guide to understanding the invisible paths resistance uses to distract, prevent, or stop before one even begins their work.
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.
