When I look back on my past and think how much time I wasted on nothing, how much time has been lost in futilities, errors, laziness, incapacity to live; how little I appreciated it, how many times I sinned against my heart and soul-then my heart bleeds. Life is a gift, life is happiness, every minute can be an eternity of happiness.

The greater the stupidity, the greater the clarity. Stupidity is brief and guileless, while wit equivocates and hides. Wit is a scoundrel, while stupidity is honest and sincere.

And why are you so firmly, so triumphantly, convinced that only the normal and the positive--in other words, only what is conducive to welfare--is for the advantage of man?
