It's not what happens to you, but how you react to it that matters.

We can't control the impressions others form about us, and the effort to do so only debases our character.

You can be invincible, if you enter into no contest in which it is not in your power to conquer.

Act your part with honor.

When your thoughts, words, and deeds form a seamless fabric, you streamline your efforts and thus eliminate worry and dread.

Never look for your work in one place and your progress in another.

Men are not worried by things, but by their ideas about things. When we meet with difficulties, become anxious or troubled, let us not blame others, but rather ourselves. That is: our ideas about things.
