We could go on and on in both directions, which to me just says that it's not so much a lucky and/or occasional side-effect when you get love and/or affirmation nearly as much as it is one possibility out of many, and that the "art", where it exists, is someplace other than in the "mood".
I mean, I have no trouble being happy, and I have no trouble getting dark. All I ask for is quality happy and quality dark, as well as, definitely, quality ambiguity (and that's the tricky one!).
