The Reactive mode tears us down, while the Responsive mode builds us up. Adversity is certainly an opportunity to develop resilience, stress-hardiness, and even post-traumatic growth. But for a person to grow through adversity, there must also be Responsive resources present such as determination and sense of purpose. Plus most opportunities in daily life to experience and develop mental resources do not involve adversity: there is simply a moment of relaxation, gratitude, enthusiasm, self-worth, or kindness.

Breathe in such a way that your inhalation and exhalation are the same duration; for example, count one, two, three, four in your mind while inhaling, and one, two, three, four while exhaling. At the same time, imagine or sense that you’re breathing in and out through the area of your heart. As you breathe evenly through your heart, call to mind a pleasant, heartfelt emotion such as gratitude, kindness, or love — perhaps by thinking about a happy time, being with your children, appreciation for the good things in your life, or a pet. You can also imagine this feeling moving through your heart as part of the breath. Try this for a minute or longer — you’ll probably be quite struck by the results.

There is no killing the wolf of hate; the aversion in such an attempt would actually create what you’re trying to destroy. But you can watch that wolf carefully, keep it tethered, and limit its alarm, righteousness, grievances, resentments, contempt, and prejudice. Meanwhile, keep nourishing and encouraging the wolf of love.

We develop mental resources in two stages. First, we need to experience what we want to grow, such as feeling grateful, loved, or confident. Second — critically important — we must convert that passing experience into a lasting change in the nervous system.
