Johann Wolfgang von GoetheWhen intelligent and sensible people despise knowledge in their old age, it is only because they have asked too much of it and of themselves.
Johann Wolfgang von GoetheThere are but two roads that lead to an important goal and to the doing of great things: strength and perseverance. Strength is the lot of but a few privileged men; but austere perseverance, harsh and continuous, may be employed by the smallest of us and rarely fails of its purpose, for its silent power grows irresistibly greater with time.
