We never really know what we want until after we get it. If after we get it, it makes life more miserable, we know that isn't what we wanted. If it makes our life wonderful, we know this is a strategy which will meet out need. That's why Paul Tillich, the theologian says we need to sin courageously. You ask for what you want, hoping to meet your needs. If you get it and it makes life worse, you learn that this isn't what I want.
Marshall B. RosenbergWhat evidence is there that we've adequately empathized with the other person?

We can become aware of this phenomenon by noticing a corresponding release of tension in our own body.
