Childhood is our most valuable resource. We must protect and cherish it, as it is unique and one-of-a-kind. Enthusiasm is the driving force of children and also the driving force in all the stories that inspire us. Enthusiasm gives us wings and makes us brilliant time and again. André Stern shares stories of children whose enthusiasm leads to the highest concentration, greatest joy, and deepest satisfaction. He also tells of adults whose passion was able to move mountains, including a carpenter, a guitar maker, a NASA astronaut, and a young publisher. And about how we can rediscover our own enthusiasm.
