“All the time you're saying to yourself, 'I could do that, but I won't,' — which is just another way of saying that you can't.”

“He who has talent in him must be purer in soul than anyone else. Another will be forgiven much, but to him it will not be forgiven. A man who leaves the house in bright, festive clothes needs only one drop of mud splashed from under a wheel, and people all surround him, point their fingers at him, and talk about his slovenliness, while the same people ignore many spots on other passers-by who are wearing everyday clothes. For on everyday clothes the spots do not show.”
― Nikolai Gogol, The Collected Tales of Nikolai Gogol
