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.

The actual effort that you can exert upon the universe is fairly limited.

My lawnmower can't change in the way that my son can or that I can.

The universe is not particularly concerned with you.

If you start the day not really expecting substantial change, but anticipating some small new revelation or some small alteration, then over time you're able to find them in more places.

Play becomes a distraction, something you don't really need to do. It's not for serious people. They work hard, they don't play hard. Yes, you can say play hard, but that really means, keep working hard, right?

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.
