"For me, filmmaking is an ongoing self-reflection process. I kind of push everything to the edge. I feel very exposed and fragile when I make a film. It's a process of dealing with loneliness. And it's also very dramatic - because while you are working on a film, you just realize how incapable you are of dealing with all these things. And you open yourself up, and it's like your heart is utterly exposed. And it's very tiring on a daily basis."
