Winning is not the goal of governing; providing an environment that nurtures our humanity is. That means those who believe in and practice democracy must graciously allow and even celebrate the opinions of others as much as we claim to celebrate democracy itself. That means, sometimes, not winning.
A “better life” is never more than a better experience of it, not any quantifiable aspect of it. “Better” is what you, and you alone, know about your life. It is not measurable, nor does it ever need to be. Measuring is only necessary when you want to communicate value to another. But your life is yours alone; it can never be experienced by another.
