Winning, losing and participating have equal importance. Each of us needs to experience both winning and losing in order to know how to participate in the best way for ourself and others. If you always lose, you lose hope and drive and you will cease participating, or at least you will not participate to your fullest. If you always win, you begin to feel superior, but more importantly, you do not have the benefit of learning from mistakes and failure which leads to self-improvement.
I believe that many of the challenges we have in global relations result from an imbalance in winning and losing. And that starts, not at a country level but at a personal level. I try to cherish my mistakes as much as my successes. I need both to keep participating.
