in hell all is sorrow, and on earth, which is in between, we find both.
We live between two extremes and partake of both.
Luck changes : not all is happiness and not all is adversity. This life is a zero : by itself it is nothing. Add the heavens, and it is much. Indifference to the world's variety is prudence; the wise care little for novelty. Our lives fold and unfold like theater, so be careful to end well.
