My father was a progressive farmer, and was always ready to lay aside an old plough if he could replace it with one better constructed for its work. All through life, I have ever been ready to buy a better plough.

You find that all men are successes or failures. Success is the stamp of truth. I will say all men who fail to place their feet on the dome of facts do so by not sieving all truth and throwing the faulty to one side.
