Mastery requires endurance. Mastery, a word we don’t use often, is not the equivalent of what we might consider its cognate—perfectionism—an inhuman aim motivated by a concern with how others view us. Mastery is also not the same as success—an event-based victory based on a peak point, a punctuated moment in time. Mastery is not merely a commitment to a goal, but to a curved-line, constant pursuit.

Play allows us to maintain curiosity while learning.

The pursuit of mastery is an ever-onward almost.

To reach an audacious goal, we sometimes benefit from having it lie just beyond our grasp.

Masters are not experts because they take a subject to its conceptual end. They are masters because they realize that there isn't one. On utterly smooth ground, the path from aim to attainment is in the permanent future.

Success is a label that the world confers on you, but mastery is an ever-onward 'almost.'

Grit is not just simple elbow-grease term for rugged persistence. It is an often invisible display of endurance that lets you stay in an uncomfortable place, work hard to improve upon a given interest, and do it again and again.
