Sometimes, I think, our brains will keep running long after we're gone. It's that wind-up toy phenomenon--we've spent so many years letting our thoughts run the same track that it's all we can see and, when tuning into the inner monologue, it's certainly all we can hear.
That's why creative thought, creative problem solving, is so vital--it's food for the spontaneous self, that aspect of our personality so necessary for optimism, for joy, for ongoing, eternal energy.
So if the world doesn't stop you short every once in a while, stop yourself, and look at where you are. Then, just for the heck of it, choose another path.
