I once read that the definition of insanity is doing the same thing over and over and expecting different results. I fundamentally disagree with this idea. I think that doing the same thing over and over and expecting different results is the definition of hope. We might keep making mistakes but the struggle gives us a sense of empathy and connectivity that we would not experience otherwise. I believe this empathy improves our ability to see the unseen and better know the unknown.
