Guard your roving thoughts with a jealous care, for speech is but the dealer of thoughts, and every fool can plainly read in your words what is the hour of your thoughts.

No man ever got very high by pulling other people down. The intelligent merchant does not knock his competitors. The sensible worker does not knock those who work with him. Don't knock your friends. Don't knock your enemies. Don't knock yourself.

All experience is an arch wherethrough gleams that untravelled world whose margin fades for ever and for ever when I move.
