There are two types of designers: Lennons and McCartneys. As a John Lennon, you create work that is message-driven, stark and serious, but you run the risk of seeming pretentious and/or naïve. (In John Lennon's defense, he was unfortunately married to the world's worst art director.) To be a Paul McCartney, on the other hand, means creating beautiful, meticulously crafted graphic design pop music, heavy on style but light on content. While either can be successful on its own (I love Wings), the best design employs both ideology and style. (See: popular music group "The Beatles").
Kind of a brilliant analogy, no? Be sure to check out the rest. I got a good laugh.
