Pay as you go is the philosopher's stone.
Don't reward bad behavior. It is one of the first rules of parenting. During the financial cataclysm of 2008, we said it differently. When we bailed out banks that had created their own misfortune, we called it a 'moral hazard,' because the bailout absolved the bank's bad acts and created an incentive for it to make the same bad loans again.
While it's really hard to do, at the same time, I'm escaping my body, which I really want to do. I'm living someone else's life. I get very intensely into the story, into the interviews and the research. I'm experiencing things along with my subjects. I have a freedom I don't have in my physical life.
