“If a person is constantly evolving, constantly reading new material and being exposed to new material and growing in life, then you're becoming, hopefully, a more intelligent and well-rounded individual. If you're not then something's wrong and you're sliding back in the other direction.”
“The last thing I'd learn, well into my career, was how to get on, how to say hello, how to get in with the audience.”
“Anyone who has never made a mistake has never tried anything new.”
