He who knows himself is enlightened.
Lao Tzu

The sage does not hoard. The more he helps others, the more he benefits himself, The more he gives to others, the more he gets himself. The Way of Heaven does one good but never does one harm. The Way of the sage is to act but not to compete.
Lao Tzu

Man's enemies are not demons, but human beings like himself.
Lao Tzu

I think the person who takes a job in order to live - that is to say, for the money - has turned himself into a slave.
Joseph Campbell

The opportunity to secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself.
Sun Tzu

A man who does not think for himself does not think at all.
Oscar Wilde

Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth.
Oscar Wilde

To vilify a great man is the readiest way in which a little man can himself attain greatness.
Edgar Allan Poe

What is necessary to change a person is to change his awareness of himself.

Abraham Maslow

Whoever renders service to many puts himself in line for greatness - great wealth, great return, great satisfaction, great reputation, and great joy.
Jim Rohn

Jim Rohn

If he have faith, the believer cannot be restrained. He betrays himself. He breaks out. He confesses and teaches this gospel to the people at the risk of life itself.
Martin Luther

He that has eyes to see and ears to hear may convince himself that no mortal can keep a secret. If his lips are silent, he chatters with his fingertips; betrayal oozes out of him at every pore.
Sigmund Freud

The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom.
Plato

For a man to conquer himself is the first and noblest of all victories.
Plato

There's a victory, and defeat; the first and best of victories, the lowest and worst of defeats which each man gains or sustains at the hands not of another, but of himself.
Plato

No man is so foolish but he may sometimes give another good counsel, and no man so wise that he may not easily err if he takes no other counsel than his own. He that is taught only by himself has a fool for a master.
Hunter S. Thompson

Positiveness is a good quality for preachers and speakers because, whoever shares his thoughts with the public will convince them as he himself appears convinced.
Jonathan Swift

Man is a universe within himself.
Bob Marley
