"Know the true value of time...."

“Know the true value of time: snatch, seize every moment of it. No idleness, no laziness, no procrastination; never put off till tomorrow what you can do today.”

Philip Dormer Stanhope, 4th Earl of Chesterfield was a British statesman, diplomat, man of letters, and an acclaimed wit of his time. This quote was from a letter to his son.
