Pressfield calls it Resistance - "It’s our own tendency—yours and mine and everyone’s—to yield to procrastination, self-doubt, fear, impatience, self-inflation, self-denigration, distraction, laziness, arrogance, complacency, and perfectionism.

It’s fear of success. Fear of humiliation. Fear of destitution. It’s our inability to defer gratification, to acquire and act with self-discipline, self-validation, and self-reinforcement. Resistance is our tendency to self-sabotage, fail to start, and fail to finish"
