Speaking Of Love (1980)
Context: Go around — listen to how many times a day you say, "I love" instead of, "I hate." Isn't it interesting that children, as they learn the process of language, always learn the word "no" years before they learn the word "yes"? Ask linguists where they hear it. Maybe if they heard more of "I love, I love, I love" they'd hear it sooner and more often.

“Happiness isn't something you experience; it's something you remember.”
As quoted in Time (28 August 1972).
