Organised around a simple metaphor of a dipper and a bucket How Full is Your Bucket? shows how even the smallest interactions we have with others every day profoundly affect our relationships, productivity, health, and longevity. Coauthor Donald O. Clifton studied the effects of positive and negative emotions for half a century, and he and his colleagues interviewed millions of people around the world. Their discoveries contributed to the emergence of an entirely new field: Positive Psychology. These same discoveries are at the heart of How Full is Your Bucket?
