Finally, there is the creative role of the subconscious, which solves problems during sleep and presents the answers during a morning shower or after a midday snooze. "I once had a brilliant engineer working with me who insisted his best ideas came to him while he was napping," said Wyeth. "Certainly, there are examples of this from the lives of Descartes, Leibnitz, Milton and Rossini, who claimed that their best thinking took place under a blanket. I mention this not because I am suggesting that every engineering lab should be equipped with beds, but rather that we ask ourselves whether we offer our colleagues or employees an environment that nurtures creativity."
