In order to provide an efficient and effective antidote to burnout, Dr. Hammer created GAIN Without Pain, a four-step process of meditation and mindfulness. GAIN is an acronym for Gratitude, Acceptance, Intention, and Nonjudgment. GAIN practice can substantially reduce stress and increase well-being in as little as three minutes a day.
