You don't want to be told, "Hey, do whatever you want." That's what we think of when we think of play. It's the thing where you get to do whatever you come up with in your own mind, all bets are off, there's no boundaries.

The idea of thinking of our relationships with people as also being structured by limitations and constraints can be useful.

You can experience play at work, not because you're messing around or wasting time or something, but because you're looking really deeply and seriously at things and asking what is possible, what can be done with them, what new ideas might emerge?

Normally if you're dating, you're looking for compatibility, and then the moment that there's incompatibility, you're like, "Well, swipe left on that, let's just keep looking." In some ways I think the same lessons apply to people that apply to objects. It's just much easier to see that lesson in things because they're these fixed intangible lumps of stuff. People are not. They can change.

With sports and games, you have fun despite working very hard, even despite failing repeatedly. Even the fun of a night out, you have to get somewhere and do all the conversational, social work of being out. There's effort involved. But then when you're finished, you can conclude, "Actually there was something gratifying about the hardship that I just encountered." That discovery of novelty is where the molten core of fun is.

Generally speaking, when people use the word fun, it's like a placeholder. You know, "How was your evening?" "Oh it was fun."

There are things about us that make us who we are, personality traits, or capacities that we have, or knowledge we possess or that we don't possess, habits we have that are good or bad.
