Strong hope is a much greater stimulant of life than any realized joy could be.

To stay cheerful when involved in a gloomy and exceedingly responsible business is no inconsiderable art: yet what could be more necessary than cheerfulness? Nothing succeeds in which high spirits play no part. Only excess of strength is proof of strength.

Enjoy life. This is not a dress rehearsal.

What if a demon were to creep after you one night, in your loneliest loneliness, and say, 'This life which you live must be lived by you once again and innumerable times more; and every pain and joy and thought and sigh must come again to you, all in the same sequence. The eternal hourglass will again and again be turned and you with it, dust of the dust!' Would you throw yourself down and gnash your teeth and curse that demon? Or would you answer, 'Never have I heard anything more divine'?

Hope in reality is the worst of all evils because it prolongs the torments of man.
