In America, we hurry-which is well; but when the day's work is done, we go on thinking of losses and gains, we plan for the morrow, we even carry our business cares to bed with us...we burn up our energies with these excitements, and either die early or drop into a lean and mean old age at a time of life which they call a man's prime in Europe...What a robust people, what a nation of thinkers we might be, if we would only lay ourselves on the shelf occasionally and renew our edges!
Mark TwainWhen I was fourteen, my father was so ignorant I could hardly stand to have him around. When I got to be twenty-one, I was astonished at how much he had learned in seven years. See what happens when you "know it all", at any stage of life? Farther down the track you may see clearly how certain personal opinions, held onto too tightly, could be fogging up the view, and providing incorrect insight. Prosperity is the best protector of principle.
