In the beginning, I loved being famous, but now I am tired of it and I would like to go back to my freedom.

I'm used to always deciding everything myself. It's a blessing, but also a terrible defect.

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.'
