Was ich weiß, kann jeder wissen. Mein Herz hab' ich allein. - Johann Wolfgang von Goethe

You often say to yourself in the course of your life that you ought to avoid having too much business, 'polypragmosyne' [incessant activity], and, more especially, that the older you get, the more you ought to avoid entering on new business. But it's all very well saying this, and giving yourself andothers good advice. The very fact of growing older means taking up a new business; all our circumstances change, and we must either stop doing anything at all or else willing and consciously take on the new role we have to play on life's stage.

Wer immer strebend sich bemüht,
Den können wir erlösen.
