We all need more energy, the vitality that helps us stay motivated, focused and productive in life. We know we receive energy from good nutrition, along with working out, adequate sleep and maintaining positivity. But there is another major source for the energy we need: having the right kinds of relationships with others. Not the ones that drain us, but the ones that refuel us.

In his new book, Dr. John Townsend, psychologist, leadership expert and coauthor of the New York Times bestselling Boundaries, shows you how we need the fuel of Relational Nutrients from others, and, in turn we can then provide them to others.

Our bodies require physical nutrients to stay healthy. If we don't take enough iron, we can develop anemia. Too little calcium can lead to bone disease. In the same way, John identifies the key Relational Nutrients that we need. As we experience these critical elements from others, we grow mentally and emotionally more sharp and healthy. And as we give these elements back, others benefit as well.

Finally, Dr. Townsend details the specific types of people who can either be energy sources or energy drains, and gives concrete steps to help you cultivate relationships with those who will help you be all you were meant to be.

The person who taught you how to have boundaries now helps you to experience the best from those people you have allowed into your boundaries.
