I read Awesomely Simple by John Spence today.  It is an excellent book that contains some of the best lessons that I learned in his "Strategies for Success" workshop, along with a few additional insights that he has discovered over the years.  One quote in the chapter about developing a "Vivid Vision" particularly struck me: "If the vision is written down in a hundred places, painted on banners, and carved in a giant rock in front of the building but is not a living part of the culture, then it is the same as not having one."
