I just dug this out the other day and my wife asked me where it was from. I always thought it had just been written by someone at Apple, and that is what Wiki says. But I have also seen it attributed to Jack Kerouac, e.g.: http://quotesgram.com/img/jack-kerouac-quotes-about-life/13096682/ Anyone know which is correct? If it wasn't from Kerouac, any idea why it has been attributed to him? Is it just that the crazy ones quote gets mixes up with this one of Kerouac: "The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars."
