Bill Watterson- A Cartoonist's Advice

They didn't, it's someone writing about Watterson's career path and using old quotes. It's interesting, just not groundbreaking.

While Zen Pencils is using older written quotes (it's the theme of the comic), the recent comics documentary 'Stripped' has the honor of the first audio interview with Bill Watterson. He initially declined, but after their interactions with dozens of other cartoonists, word got to Bill that they were "the real deal" and passionate about what they were doing. Rather inspiring.
