Normally we think of play as the opposite of work. Work is the thing you have to do, and then there's play, the thing you choose to do.

The problem with fun is we really don't know what fun means at all.

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

Today, all our wives and husbands have Blackberries or iPhones or Android devices or whatever-the progeny of those original 950 and 957 models that put data in our pockets. Now we all check their email (or Twitter, or Facebook, or Instagram, or) compulsively at the dinner table, or the traffic light. Now we all stow our devices on the nightstand before bed, and check them first thing in the morning. We all do. It's not abnormal, and it's not just for business. It's just what people do. Like smoking in 1965, it's just life.

We have to always spread sugar on top of it in order that we can tolerate swallowing the things we're supposed to do, which is an incredibly depressing way of thinking about living your life. Not just that your work or your home life would be so miserable that you have to slather sugar on it, but then the sugar is all you're tasting. If that's the only way that I'm finding meaning, then we have this sort of mental diabetes that we're descending into.

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.

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.
