Tom Kelly, general manager of IDEO, the world-renowned design firm, likes to quote French novelist Marcel Proust, who famously said, “The real act of discovery consists not in finding new lands but in seeing with new eyes.” What goes for novelists goes for leaders searching to craft a novel strategy for their company, a new product for their customers, or a better way to organize their employees. In a world that never stops changing, great leaders never stop learning.
