My go-to vote as well. Some of my favorite passages pertain to the awareness of-and management of- one's internal motivation and thought process when attempting to do good work.
"So the thing to do when working on a motorcycle, as in any other task, is to cultivate the peace of mind which does not separate one’s self from one's surroundings. When that is done successfully then everything else follows naturally. Peace of mind produces right values, right values produce right thoughts. Right thoughts produce right actions and right actions produce work which will be a material reflection for others to see of the serenity at the center of it all."
