Ultimately, the only way to be fulfilled is to constantly grow and to contribute in a meaningful way to other people, to the world. And in order to grow, all of us have to be willing to let go of our fear and let go of who we are, and we've got to set standards and we've got to challenge ourselves.

And I think that's the part that has to be focused on. We need to develop the emotional and spiritual muscles to deal with whatever challenges show up.
