You can't play the same game every day for years. New games are key.

Game developers know that people have more fun when they're in large groups. They feel more fired up when the challenges are more epic.

Things like depression and obesity are global challenges.

A traumatic event doesn't doom us to suffer indefinitely. Instead, we can use it as a springboard to unleash our best qualities and lead happier lives.

Reality is broken and we need to make it work more like a game.

When we play a game, we tackle tough challenges with more creativity, more determination, more optimism, and we're more likely to reach out to others for help.

I see a future in which games once again are explicitly designed to improve quality of life, to prevent suffering, and to create real, widespread happiness.
