The more you're drowning in familiarity, the better the fun is. It requires less novelty to produce even more gratification. And it's something that didn't come from you. It was about the other thing - the thing you were experiencing, or the people you were with, or the mechanism you were operating, or whatever it might be.

When we think about play and games and the situations in which having fun is seen as an outcome, they often have to do with repetition. You're returning to something again, and even despite that similarity, you squeeze something new out of it.

I think the most important thing to realize about play is that it's this thing that's in stuff, it's not in you.

Play isn't you being clever, or finding a trick, or finding a way of covering over your own misery, or persuading someone to do what you want. It's the process of working with the materials that you find and discovering what's possible with them.

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.

I think this dichotomy or opposition between work and play, between leisure and serious stuff, is definitely a bad way of thinking about the useful insights that play provides.

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.
