“The thing is, I get bored easily. So if my manga was just about the action, or comedy, or tear-jerking moments, I would get bored. I change the style of the series to keep up my motivation to draw. [...] Humans can only come up with new ideas when they’ve reached their limits. When I finish a manuscript, I am completely exhausted.”
-- Eiichiro Oda, the 38-year-old creator of One Piece, crediting a short attention span and sheer exhaustion as the secrets behind his hit pirate adventure, which has more than 345 million copies in print worldwide. He reveals that he doesn't sleep or eat much when he's working.
