Someone's sitting in the shade today because someone planted a tree a long time ago.

The meaning I picked, the one that changed my life: Overcome fear, behold wonder.

As knowledge increases, wonder deepens.

Tears are often the telescope by which men see far into heaven.

The most authentic thing about us is our capacity to create, to overcome, to endure, to transform, to love and to be greater than our suffering.

Nurture your minds with great thoughts. To believe in the heroic makes heroes.

Everyone here has the sense that right now is one of those moments when we are influencing the future.

Put your heart, mind, and soul into even your smallest acts. This is the secret of success.

It is not ignorance but knowledge which is the mother of wonder.

I have looked into your eyes with my eyes. I have put my heart near your heart.
