“Freedom is only to be found where there is burden to be shouldered. In creative achievements this burden always represents an imperative and a need that weighs heavily upon man’s mood, so that he comes to be in a mood of melancholy. All creative action resides in a mood of melancholy, whether we are clearly aware of the fact or not, whether we speak at length about it or not. All creative action resides in a mood of melancholy, but this is not to say that everyone in a melancholy mood is creative.”
