I never got into making documentaries for any kind of success, because documentary careers are generally ones of prolonged failures.

I always tell aspiring documentary filmmakers, 'You have to go into it because you love it; if you go into it for the money, you're an idiot.' The number one prerequisite is you have to be intensely curious. If you love learning and trying to make people figure out what makes people tick, it's the best job in the world.

There was no model how to make a documentary production company work. I figured it out as I went along.
