Mastering isn’t a survival instinct; it’s an urge to excel. Mastering is one of the experiences that delineates us from animals. It is striving to be more tomorrow than we are today; to perfectly pitch the ball over home plate; to craft the perfect sentence in an article; to open the oven and feel the warm, richly-scented cloud telling you dinner is going to be absolutely extraordinary. We humans crave perfection, to be masters of our domain, to distinguish ourselves by sheer skill and prowess. -- Joesgoals.com

We fail to realize that mastery is not about perfection. It's about a process, a journey. The master is the one who stays on the path day after day, year after year. The master is the one who is willing to try, and fail, and try again, for as long as he or she lives. -- George Leonard, Mastery.
