Same, except that I would be so ridiculously excited that I had sold enough books and garnered enough interest to justify making even the crappiest of movies. It wouldn't be "Yeah, yeah, whatever," it would be "Hell yeah sign me up is there anything I can do?"
Yeah. And if you have even one hit along the lines of a Twilight or Hunger Games, you can spend the rest of your life writing whatever you want, no matter how artsy or inaccessible, and at least from a financial perspective it won't matter if anyone ever reads it. You become free.
