Orison Swett Marden

A smile is a true life force, the only one capable of moving the immovable.

Success is not achieved by celebrating victories but by overcoming failures.

A pebble in the bed of a humble brook can change the course of a river.

True science is far above political passions, racial and language differences, and religious sectarianism.

A penny well spent is worth more than a penny saved.

Luck is nothing more than the ability to take advantage of favorable opportunities.

Economics consists of knowing how to spend, and savings consists of knowing how to save.

I prefer to know how to appreciate what I cannot have, than to have what I am not capable of appreciating.
