Much of progress is imperceptible: the daily changes not visible in the mirror, not obvious in technique repetition, not ostensible in character development. Like cutting a gemstones, 1,000 hits may not make any visible change in the state of the gem, but the potentiality accumulates, and then 1,001 strokes creates a perfect cut. We misperceive the final strike as the “right way” rather than the culmination of the right persistence.
The definition of insanity is repeating an unsuccessful behavior and expecting different results. The difference between insanity and persistence is commitment, knowing the difference is wisdom.
