 Let me just put on the table here a really key psychological term called anti-fragility. It's a term, it refers to the property of systems that are not fragile. They actually, you know, something is fragile, you've got to protect it. Like glass is fragile, you don't want it to bang around, it'll break. But there's some things that need to bang around. They need to be stressed and challenged in order to develop properly.
