“If I were to begin life again, I would devote it to music. It is the only cheap and unpunished rapture upon earth. ”

“if I were to begin my life again, I should want it as it was. I would only open my eyes a little more.”

“If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music.”

“I've decided that if I had my life to live over again, I would not only climb more mountains, swim more rivers, and watch more sunsets; I wouldn't only jettison my hot water bottle, raincoat, umbrella, parachute, and raft; I would not only go barefoot earlier in the spring and stay out later in the fall; but I would devote not one more minute to monitoring my spiritual growth. No, not one.”

“The only difference was, you could play the music again and again; a life plays only once.”

“But I love your feet only because they walked upon the earth and upon the wind and upon the waters, until they found me.”
