For me it's a dedication to your real interests. It's an ability to be open-minded. Without an open-minded mind, you can never be a great success. The great artists have been open-minded, even though they may seem, like Picasso, to be very directed, you can be directed and open-minded at the same time. I think you have to be really intensely serious about your work, but not so serious that you can't see the lightness that may also involve your life. You have to have that lightness too. You have to not be so heavy-handed and so ostentatious. It's very important not to be.
