Morrie: Have I told you about the tension of opposite?

Mitch: Tension of opposite?

Morrie: Life is a series of pull back and forth. You want to do one thing, but you are bound to do something else. Something hurts you, yet you know it shouldn't. You take things for granted, even you know you should never take anything for granted.

Morrie: A tension of opposite, like a pull on a rubber band. And most of us live somewhere in the middle.
