“Quantification, like surgery, is an excellent thing in the right place, but a very bad topic for obsession. Unless you know just what you are counting--unless you are sure that the things counted are standard units--and unless you understand what is proved by results of your counting, quantifying provide you only with the outward show of science, a mirage, never the oasis.”

“Many of the things you can count, don't count. Many of the things you can't count, really count.”

“Whenever you look back and say, "If," you know you're in trouble. There's no such thing as "if." The only thing that counts is what really happened.”

“I'm a perfectionist. I like to get it right. I like to get it good. And you know, writing songs is not -- it's not the kind of thing that you can count on every day. You never know what's going to come or if it's going to come. So you -- you know, it's an uncertain kind of a thing.”

“The metric system did not really catch on in the States, unless you count the increasing popularity of the nine-millimeter bullet.”

“Unless you do the right things, the right things will not happen to you.”

“I never lie, even to this day. Not even a little. Unless you count playing pranks on people, which I don't. That's comedy. Entertainment doesn't count. A joke is different from a lie, even if the difference is kind of subtle.”

“You must understand that ordinary efforts do not count; only superefforts count.”

“It's what you learn after you know it all that counts.”

“Knowing what's right doesn't mean much unless you do what's right.”
