The perennial adage directed at artists to find their own voice is reprised here by filmmaker Christopher Nolan:
You have to cross into this world of just pleasing yourself, just doing something because you want to do it. It was a very valuable lesson. The truth is you have to hang on to your own belief. At the end of the day, all you really have is your own belief, your own passion. You can't ignore the feedback. But you tell the story because you love it.
