&gt; If you were to go back to the three things that people need—mastery, belonging, and autonomy—I&#x27;d add a fourth, after basic necessities have been met. It’s the attitude or the worldview that you bring to life. And that worldview can be characterized, just for simplicity, in one of two fashions: One extreme is a kind of scarcity-minded approach, that my win is going to come at somebody else&#x27;s loss, which makes you engage in social comparisons. And the other view is what I would call a more abundance-oriented approach, that there&#x27;s room for everybody to grow.<p>The best part of his analysis, IMHO.  I don&#x27;t even like being around zero-sum people.
