Lost wealth may be replaced by industry, lost knowledge by study, lost health by temperance or medicine, but lost time is gone forever.

We learn wisdom from failure much more than from success. We often discover what will do, by finding out what will not do and probably he who never made a mistake never made a discovery.

Wisdom and understanding can only become the possession of individual men by travelling the old road of observation, attention, perseverance, and industry.

Practical wisdom is only to be learned in the school of experience. Precepts and instruction are useful so far as they go, but, without the discipline of real life, they remain of the nature of theory only.

The experience gathered from books, though often valuable, is but the nature of learning whereas the experience gained from actual life is one of the nature of wisdom.
