High Performance Habits: How Extraordinary People Become That Way (Brendon Burchard)
This is one of those books that I immediately wanted to start over from the beginning right after finishing it. It has so much good information packed into it that I really felt the need to reread it so that I could comprehensively absorb it all. In it, Brendon discusses what he calls the HP6 - six habits that all high performers attribute their success to. These habits are Clarity, Energy, Necessity, Productivity, Influence, and Courage. He not only examines each in depth but also provides easy-to-follow Performance Prompts, Worksheets, and more. Highly recommend.
