This guy gets it. "Do what's best for yourself and the group". Nash proved it is the best way forward in an economic sense. I believe this principal can be used to help better direct your life in general.
Inequality is the cause of most of the world's suffering in my opinion. Our success as countries is measured by GDP's and other economic metrics. Yet countries that have the most impressive economic figures, tend to have the least impressive figures when it comes to social metrics, like crime, violence, and mental health issues.
Adams theory was incomplete, Nash improved it and we are still not listening. Whether it be in life or in economics itself we seem to be using the "every man for himself" approach, when it is mathamatically proveable there is a better way.
I was listening to cage-fighter Chael Sonnen describe advice he received from his father that you essentially have no friends in the 9 to 5 world. Everybody is out to get you, and you have to fight for every inch that you move. While true from a practical perspective, I also thought that it's an incredibly tragic way to live life.
At some point, you do have to depend on other people. We're not meant to live life in solitude. This doesn't mean to throw away your competitive spirit; rather, the lesson I received was to channel that spirit towards positive, productive endeavors.
Thanks for sharing your insights...it's sorely needed in the present age we live in!
