How to Think Like Leonardo DiVinci by Michael J. Gelb. At a time when innovation rises as the golden apple for the future, studying DiVinci offers a master's lesson in discovery, invention, creativity, global thinking and humanity. A master-thinker himself, Gelb breaks up DiVinci's mental activities into discreet functions. This is a book that can be picked up over and over again. I myself could spend a lifetime on learning how to ask the curious, deeper questions. Journaling, drawing, conversation and experimentation are all part of a course of action that Gelb carefully outlines. Skim it for the antipasto and come back for the next course. I guarantee you won't go away hungry.
