Yep. The only way to make really good, memorable art is to be at least a little bit crazy about it. You have to want to show the world the thing you've created, and you have to choke down any sense of hesitation, any apprehension about your work being seen. You have to be willing to try,
and fail, as many times as it takes to make something you're proud of. If
you're not crazy about the story/character/setting you've created, how can you expect anyone else to be?
(That's why all the blockbuster movies these days suck, BTW. They're all designed by committees who are only interested in "broad appeal"; in creating a
product for the sake of profit, not in making
art. In literature, this is sometimes called
"Extruded Book Product"; I'm not sure if we have a term for a Hollywood-specific content mill yet.)
