Jean-Paul Sartre said this quote
“ You didn't succeed. Well, what of that? There's nothing to prove, you know, and the revolution's not a question of virtue but of effectiveness. There is no heaven. There's work to be done, that's all. And you must do what you're cut out for; all the better if it comes easy to you. The best work is not the work that takes the most sacrifice. It's the work in which you can best succeed. ”
