Thou oughtest in every deed and thought so to order thyself, as if thou wert to die this day.
Do not act as if thou wert going to live ten thousand years. Death hangs over thee. While thou livest, while it is in thy power, be good.
Do not, my soul, seek immortal life, but exhaust the limits of the possible.
Life is a journey, not a destination.
Trust thyself: every heart vibrates to that iron string.
A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages. Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty.
