Truth, like beauty, is neither created nor lost.

Humility is what you strive for when you’ve failed at everything else.

This life’s hard, but it’s harder if you’re stupid.

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve.

Don’t tell your problems to people: eighty percent don’t care, and the other twenty percent are glad you have them.

After silence that which comes nearest to expressing the inexpressible is music.

Everybody should be quiet near a little spring and listen.

We are surrounded by mystery, by what we don’t know and, more dramatically, by what we can’t know.

I very frequently get the question: “What’s going to change in the next ten years?” And that is a very interesting question; it’s a very common one. I almost never get the question: “What’s not going to change in the next ten years?” And I submit to you that the second question is actually the…

No one can build you the bridge on which you, and only you, must cross the river of life. There may be countless trails and bridges and demigods who would gladly carry you across; but only at the price of pawning and forgoing yourself. There is one path in the world that none can walk…

People are just as wonderful as sunsets if I can let them be… When I look at a sunset as I did the other everning, I don’t find myself saying, “Soften the orange a little on the right hand corner.” … I don’t try to control a sunset. I watch with awe as it unfolds.
