Hi John
It was Jack Kirby said that. I found it buried in the author biographies for ‘
Seven Miles a Second‘, a Vertigo graphic novel from the 1990s. The artist on that book (James Romberger) was apparently told that by Kirby at a convention once. I then used it as the epigraph (is that the write word?) at the beginning of Hicksville (and, before that, a Pickle as well).But apparently (now that I’ve done some googling), Charles Schulz once said: “cartooning will destroy you. It will break your heart.” So there’s something of a theme emerging here… 
Cheers
Dylan
