In the War of Art, Steven Pressfield writes about the Principle of Priority, which makes two significant but related points. The first is that you must know the difference between what is urgent and what is important. The second is that you must do what is important first. The professional places discipline above what is pressing because he or she “knows that by toiling beside the front door of technique, he leaves the room for genius to enter by the back.” Making a habit of doing the harder thing on a consistent basis changes everything by inviting the sub-conscious to participate in the creative process.
