Everybody always feels that they're right even if they're wrong and that's what a whole actor's career is built around rationalizing your way into whatever character you're playing.

I do believe in self-help.

You're as young as you feel. As young as you want to be. There's an old saying I heard from a friend of mine. People ask him, "Why do you look so good at your age?" He'll say, "Because I never let the old man in." And there's truth to that. It's in your mind, how far you let him come in.

A lot of times people get to a certain age and they quit. I always felt sorry for the Frank Capras, the Billy Wilders, directors like that, because they quit in their sixties. Why would you quit? Think of the great work they could've done in their sixties, seventies, and on up.

I do believe if one keeps busy it's very good for a person. In fact, people are always rushing into retirement and we read in Europe that people there are talking about their retirement age and moving it to 67 or something. Well, back when they started retirement funds and everything, the average age was 70 or 60, and then all of a sudden now it's 80, and so. [...] And so you keep in shape, you keep yourself mentally in shape. And if you keep yourself mentally in shape, chances are physically it will follow suit.

Directing is more like you're being a psychologist and you're kind of analyzing the situation and evaluating each person for their idiosyncrasies.

You have to go with your instincts. I remember when I was about to make "Fistful of Dollars" a big article came out that said, "Italian Westerns are finished." I said, "Swell." Then, of course, the film came out, and it did something. I'm so glad for the dozens of times I haven't listened along the way.
