Confucius say we can learn wisdom by thinking about things first, copying what other people do, or bumping our heads which he thought was a bad idea. A Chinese factory manager was concerned that so many workers were slipping on these metal steps that he politely advised them to fall down carefully.

We’re worried about this development. What if they bumped their heads when they slipped on a patch of oil? Might the boss decide they were disobedient, and refuse them worker compensation? That would not be fair!
