Creativity isn't born, it's cultivated--this innovative guide distills the work of extraordinary artists and thinkers to show you how.   All the imagination needs to be fruitful is exercise. Robert and Michele Root-Bernstein identify the thinking tools employed by history's greatest creative minds--from Albert Einstein and Jane Goodall to Amadeus Mozart and Virginia Woolf--so that anyone with the right mix of inspiration and drive can set their own genius in motion. With engaging narratives and ample illustrations, Robert and Michele Root-Bernstein investigate cognitive tools as diverse as observing, imaging, recognizing patterns, modeling, playing, and more to provide "a clever, detailed and demanding fitness program for the creative mind" (Kirkus Reviews).
