The aim of living is life itself.
The finished man, you know, is difficult to please; a growing mind will ever show you gratitude. --Faust 1, lines 182-3
He alone deserves liberty and life who daily must win them anew.
Mastery is often taken for egotism.
He who does not expect a million readers should not write a line.
Life teaches us to be less harsh with ourselves and with others.
