Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it. — Johann Wolfgang von Goethe. German writer and polymath (1749–1832)
Against criticism a man can neither protest nor defend himself; he must act in spite of it, and then it will gradually yield to him.
Genius thinks it can do whatever it sees others doing, but is sure to repent of every ill-judged outlay.
