This is a sort of spoof by Jimmy Kimmel that represents Trump's philosophy. Trump seems to like it.
I see that win-win training is still taught, and seen as a set of negotiation skills. It seemed like more when I first heard about it. It seemed revolutionary. It posited that things go best when everyone's needs are met, that aggression is worse than useless. I agree.
The opposite of winning and losing is feeling that you have enough, and being satisfied. If you are reading this, you have access to a computer and leisure time to fool around on it, and probably have adequate shelter and food as well. That's just about enough, really.
There is a basic unsatisfactoriness built-in to human life, and that is that things change and we know they will. We will grow old, sick, and die, and we know that, or at least fear it. To be satisfied we have to realize that cause and effect are complicated and a lot of things are not in our hands, and relax with that. Winning at anything won't change it. And the fact that you're not striving to win doesn't mean you're a loser.
