I started young but at every turn, listening provided a foundation for my leadership. I can say categorically that all the really excellent leaders I have known were, in my view, excellent listeners.

I did all the work at the beginning up until the point where I couldn't handle the increasingly heavy art production burden alone. I needed, and got, assistance.

Jerry picked up the technique of visualizing the story as a movie scenario; and whenever he gave me a script, I would see it as a screenplay. That was the technique that Jerry used, and I just picked it up.

I drew a picture on the back of a calendar in pencil. In those days they used to give out free calendars, I had no art paper, so I took whatever else I could.

And I agreed the feeling of action as he was flying or jumping or leaping - a flowing cape would give it movement. It really helped, and it was very easy to draw.

Clark Kent, I suppose, had a little bit of Harold Lloyd in him.

Jerry and I always felt that the character was enjoying himself. He was having fun: he wasn't taking himself seriously. It was always a lark for him, as you can see in my early drawings.
