We all know those who draw their boundaries carefully and say, "I'm only human. Nobody's perfect. I accept my limitations." And we know others who take an opposite view and say, "I can do anything I choose to do. It is in my power to change the world." And those are the ones who most often change the world.

The airplane is just a bunch of sticks and wires and cloth, a tool for learning about the sky and about what kind of person I am, when I fly. An airplane stands for freedom, for joy, for the power to understand, and to demonstrate that understanding. Those things aren't destructable.

Those who win are those who think they can.

The only thing that matters, at the end of a stay on earth, is how well did we love, what was the quality of our love?

You are life, inventing form. No more can you die on sword or years than you can die on doorways through which you walk, one room into another. Every room gives its word for you to speak, every passage its song for you to sing.

You can achieve a goal; you never really achieve your purpose, because your purpose is ongoing. It never stops.

It is by not always thinking of yourself, if you can manage it, that you might somehow be happy. Until you make room in your life for someone as important to you as yourself, you will always be searching and lost.
