We thrive not when we've done it all, but when we still have more to do.

The pursuit of mastery is an ever-onward almost.

Mastery is in constantly wanting to close the gap between where you are and where you want to be.

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

Pain is not a punishment. And pleasure is not a reward. You could argue that failure is not punishment and Success is not reward. They're just failure and success. You can choose how you respond.

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.

Completion is a goal, but we hope it is never the end.
