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.

Hope... is the companion of power, and the mother of success; for who so hopes has within him the gift of miracles.

I'm as happy a man as any in the world, for the whole world seems to smile upon me!

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

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

Good actions give strength to ourselves and inspire good actions in others.

Knowledge conquered by labor becomes a possession - a property entirely our own.

Enthusiasm... the sustaining power of all great action.
