And the world sees him as crazy. But even though everyone he encounters sees him as crazy, as he enters their lives, they become better versions of themselves.
That's what artists do.
We're, in a sense, crazy people, that change the lives of those we touch. Even though those same people may sometimes criticize us for what we do or how we do it, they need us and want us.
And we do what we do because we can do nothing else. We can't help ourselves. In the same way that Alonso Quixano could be nothing other than Don Quixote.
