If we do only what feels good and what is comfortable, we do not grow. If we do not stretch our minds, we vegetate intellectually. If we do not discipline our bodies, we become physically flabby and weak. If we do not exercise our goodwill, we stay emotionally immature.
To settle for minimum achievement is to miss the satisfaction of accomplishing more than we once thought possible. It is trite but true that we never know what we can do until we try. By accomplishing, we makes possible other achievements that we formerly may have considered to be beyond our reach.
