A book I keep coming back to (re-read every two years or so) and recommend others is "Zen and the Art of Motorcycle Maintenance". It has shaped my thinking on 'what is good' or 'what does quality' mean. As an engineer it is easy to appreciate the author slowly going insane about the details he keeps coming back to, and as a human it is invaluable to have an understanding yourself of when something is 'good'. Highly recommended.
