Good artists hustle. They stretch their limits of imagination. They welcome discomfort. The others are busy drawing more sea-shells and palm trees.

A monk hustles. Zen is tough. "Don't-know mind" does not come easy. Meditation is really hard. They put in the time and the effort where others give up and quit.
