How do these authors find the time?

I was looking at J.K. Rowling's site this afternoon, until I realized I didn't have nearly enough time in my life to plumb its depths. If I can't even find time to explore it, how did she have time to write it? Granted, she's got web designers and such folks to help her out. But, still, there's a lot of content there. Be sure to check out the "Extra Stuff" link and the "Scrapbook" link.

But, J.K. has NOTHING on the content Orson Scott Card delivers. The man is an industry, a force of nature, a steamroller of steamrollers. I'm sure there are other authors who manage similar output (on work that isn't even their "real" work). But it would be phenomenally hard to beat OSC.
