Security is an illusion. Life is either a daring adventure or it is nothing at all.

Without ambition one starts nothing. Without work one finishes nothing. The prize will not be sent to you. You have to win it. The man who knows how will always have a job. The man who also knows why will always be his boss. As to methods there may be a million and then some, but principles are few. The man who grasps principles can successfully select his own methods. The man who tries methods, ignoring principles, is sure to have trouble.

The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather in a lack of will.

The good man is the teacher of the bad,
And the bad is the material from which the good may learn.
He who does not value the teacher,
Or greatly care for the material,
Is greatly deluded although he may be learned.
Such is the essential mystery.

There is only one thing a philosopher can be relied upon to do, and that is to contradict other philosophers.

A traveler must have the back of an ass to bear all,
a tongue like the tail of a dog to flatter all,
the mouth of a hog to eat what is set before him,
the ear of a merchant to hear all and say nothing.

The most incomprehensible thing about the world is that it is at all comprehensible.
