How Full Is Your Bucket? by Tom Rath and Mary Reckmeyer (2009)
When Felix wakes up one morning, he finds an invisible bucket of water floating overhead. His grandfather explains that when people are selfish and mean to one another, a little bit of water disappears from their buckets. But when people are thoughtful and generous, their buckets will fill back up. As Felix goes about his day, he discovers that he sometimes makes people's buckets a little emptier by accident-and that they wind up emptying his bucket in return. This helps Felix understand that the way he treats others can not only make them happy, but can change how good he feels about himself. With a relatable character and a symbol that is easy to understand, How Full Is Your Bucket? For Kids puts readers on the path toward responding constructively to others' feelings and their own.
