The three things that are most essential to achievement are common sense, hard work and stick-to-it-iv-ness... Unfortunately, many of life's failures are experienced by people who did not realize how close they were to success when they gave up. I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.
Thomas A. EdisonTo Monsieur Eiffel the Engineer, the brave builder of so gigantic and original a specimen of modern Engineering from one who has the greatest respect and admiration for all Engineers including the Great Engineer the Bon Dieu.
