Sharpen the Saw: the renewal habit

Mihaly Csikszentmihalyi's term for the state of complete absorption in an activity that's challenging enough to engage all of one's skill but not so hard that it overwhelms. In flow, time disappears, self-consciousness fades, and the work itself becomes the reward. The conditions: clear goals, immediate feedback, balance between challenge and skill. Sharpen the Saw activities are most renewing when they generate flow.
