Steve Pressfield has written the most important book I've ever read on creativity and why it doesn't happen. The resistance is the most profound force in the life of the artist, the writer and the leader, and Steve has given it a name and called it out.
In this short book, Steven sells a very important and simple idea. We are victims of the resistance, an almost irresistible force in our lizard brain that shouts out our genius and pushes us to fit in instead. Once you recognize the resistance and know its name, this knowledge will change you (for the better).
In Steven Pressfield's classic The War of Art, he introduces the idea of Resistance. It's the internal force that keeps us from doing our most important creative work.
