Never Put Off

Know the true value of time; snatch, seize, and enjoy every moment of it.  No idleness, no laziness, no procrastination: never put off till to-morrow what you can do to-day.

-- Philip Stanhope, 4th Earl of Chesterfield (1694 - 1773), British statesman and man of letters, Letters to His Son on the Art of Becoming a Man of the World and a Gentleman (1774), entry for 26 December 1749
