Any phrase that suggests play is this domain that's the opposite of work, or the thing that you do when you're done working, should trouble us. Because it means that play is always relegated to the exhaust of life. It's the thing that you do after you do the important stuff, it's what you do on your own time.

If you think about the contexts in which we talk about things being fun, often there's a certain kind of misery or effort that's involved with it. The difficulty of travel, getting all your bags packed and your work done and navigating the airports and all that. That sort of struggle.

You allow yourself to discover the things that are already there when you play.

Even when we tell kids to go play, what do the kids do? They come up with a set of constraints and structures. "Oh, we're gonna build a fort out of clothes, and now that we're in the fort we're going to pretend that we're prisoners," or whatever.

I think the most important way to understand play is that it's this property that's in things. Like there's play in a mechanism. For example, there's some play in the steering column before it engages as you're turning the wheel.

The modern world is very wealthy, it's full of options. It's not like "This is the land I was born on and I have to make the most of it, and these are the people who are near me, and so they will become my family."

I think a lot of the misery that people experience comes from that sensation of boundlessness, of infinite possibility.
