To be wise about something is to think it has no need of you. Or, rather, wisdom is the thought that "it is what it is", sufficient unto itself. This can be taken to extremes, to be sure. You might realize that you're not needed at all. The euphoria of wisdom, we might say, is the thought that literally everything is going to be okay. You come back to the world when you feel that things might not be as they seem, and something has to be done. You find your place again.
