If something is solved, I can stop thinking about it. If something is solved, that means it was a problem. If something is solved, that means I don't have to change anything I'm doing. It means I'm okay. It means the Stadium of Shame is quiet, if not empty. And if a solution worked, that means I can just keep doing it, right?
Problem/solution is a closed system, and there's no such animal. Open systems eat, excrete, exchange parts of themselves with their environments, things like them and things different from them. You can't solve an animal except by killing it. When I die, I will no longer make any mistakes.
