"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!"
