First thing's first: JANE McGONIGAL HAS A NEW TED TALK OMG HOLY CRAP THIS IS AWESOME
Now that I've got that out of my system.
I remember, when I was reading "Reality Is Broken," the chapter when Jane McGonigal discusses "Super Better," the game she invented to help her through the depression and recovery after a serious injury. I don't remember, at the time, making the connection between my own depression and the variety of illnesses that other people are using Super Better to get through.
I don't know. Maybe I did think of it. There was a lot in that book that made me think, "There it is! The solution to everything!"
In McGonigal's new TED talk, she points out, much more straightforwardly, that the tools she developed are a framework for improving one's life, in exactly the sort of way that everyone, not just people suffering from serious illness, can benefit from.
It's a little embarrassing, actually, to realize that I didn't make this connection in the first place. The central theme of "Reality Is Broken" is positive psychology -- using science, psychology, analysis, and especially gamification, to move upwards from a neutral point and make life better, rather than just focusing on alleviating suffering and reducing exposure to unpleasant experiences.
The talk is great. You should watch it. You should also watch her other TED talk, which is more broadly about how gaming can make the world a better place, and read her book, Reality Is Broken, which is about using game style mechanisms to make everything better.
