[Common sense] is the best sense I know of. — Lord Chesterfield. British politician, diplomat and writer Common Sense
Wit is so shining a quality that everybody admires it; most people aim at it, all people fear it, and few love it unless in themselves.
Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.
Know the true value of time; snatch, seize, and enjoy every moment of it. No idleness; no laziness; no procrastination; never put off till tomorrow what you can do today.
