I think any comic book - or really, any book that you can read - in a sense is an educational tool in that it helps literacy. The more you read, the better you get at it. It almost doesn't matter what you read, the important thing is for young people to become readers.

If I were retired I wouldn't know what to do because I'd have to think, well, now what is it I want to do? And what I want to do is what I'm doing. I enjoy coming up with new ideas, which if I'm lucky they might be good ideas. I enjoy seeing them take shape. And I'm having fun doing it. So I wouldn't know why I'd want to retire.

I think I've got 12... Superman, Batman, Wonder Woman, The Flash, Aquaman, Plastic-Man, Green Lantern, Sandman, The Justice League, The Atom Legion of Superheroes and Teen Titans.... Just about all of their top titles.

So I'm happiest when I'm working with artists and writers, and involved in stories, whether we're talking about animation or movies or comics or television.

My biggest regret is that I don't really have time to read.

I have to force myself to get angry. But I want to show the world that there's another side to me, that I am capable of deep, deep anger and fury. They better watch out for how I'm treated.

The purpose of this is not show that I can do it better, because I think Superman is perfect. The original creation of Superman nobody could have done that better and I think Batman is pretty much a perfect character... The same with all of them. I'm just going to try to find a way to say, "If that wasn't the original idea, what would be another way to do it that would be more in my style?".
