“A person's worth is measured by the worth of what he values.”

The best revenge is to be unlike him who performed the injury.

The object of life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane.

The universe is change; our life is what our thoughts make it.

Do not act as if you were going to live ten thousand years. Death hangs over you.

The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are.

Think of yourself as dead. You have lived your life. Now, take what's left and live it properly.

If it is not right, do not do it; if it is not true, do not say it.
