It’s good for the artist to understand conflict and stress. Those things can give you ideas. But I guarantee you, if you have enough stress, you won’t be able to create. And if you have enough conflict, it will just get in the way of your creativity. You can understand conflict, but you don’t have to live with it.
In stories, in the worlds that we can go into, there’s suffering, confusion, darkness, tension, and anger. There are murders; there’s all kinds of stuff. But the filmmaker doesn’t have to be suffering to show suffering. You can show it, show the human condition, show conflicts and contrasts, but you don’t have to go through that yourself. You are the orchestrator of it, but you’re not in it. Let your characters do the suffering.
