The true price of anything you do is the amount of time you exchange for it. - Henry David Thoreau

It takes us many years to find out that Nature repeats herself annually. But how perfectly regular and calculable all her phenomena must appear to a mind that has observed her for a thousand years!

If you are describing any occurrence... make two or more distinct reports at different times... We discriminate at first only a few features, and we need to reconsider our experience from many points of view and in various moods in order to perceive the whole.

The student who secures his coveted leisure and retirement by systematically shirking any labor necessary to man obtains but an ignoble and unprofitable leisure, defrauding himself of the experience which alone can make leisure fruitful.
