Every man's plans and designs are born of imperfect minds. Therefore, man creates imperfect plans and thus has imperfect results. To expect such results and be prepared for them demonstrates the presence of wisdom. One who chases after a target of perfection soon tires. Adapting to the circumstances and carrying on demonstrates understanding. Be not defined by adversity, but by the ways that you overcome it. The mountains, the continents, the seas, have all changed and continued to do so; pebble by pebble, drop by drop; sometimes dramatically, sometimes imperceptibly, but they do change.
