Kate Marvel captures and expresses my feelings here:
We need courage, not hope. Grief, after all, is the cost of being alive. We are all fated to live lives shot through with sadness, and are not worth less for it. Courage is the resolve to do well without the assurance of a happy ending. Little molecules, random in their movement, add together to a coherent whole. Little lives do not. But here we are, together on a planet radiating ever more into space where there is no darkness, only light we cannot see.
