Calvin Coolidge

All growth depends upon activity. There is no development physically or intellectually without effort, and effort means work.

Those who trust to chance must abide by the results of chance.

Knowledge comes, but wisdom lingers. It may not be difficult to store up in the mind a vast quantity of facts within a comparatively short time, but the ability to form judgments requires the severe discipline of hard work and the tempering heat of experience and maturity.

Nothing in this world can take the place of persistence. Talent will not: nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent.

No person was ever honored for what he received. Honor has been the reward for what he gave.

It is only when men begin to worship that they begin to grow.

The business of America is business.

Don't expect to build up the weak by pulling down the strong.

Little progress can be made by merely attempting to repress what is evil. Our great hope lies in developing what is good.
