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.
