In today's episode, Dr. Cory Shaffer and Dr. Katie Nichols focus on the power and importance of gratitude. Dr. Nichols tells the story of Brenda Martinez, an American track and field athlete, who tragically missed the final qualifier for the Olympic's due to entanglement with other athletes in the 800-meter race, her primary. Dr. Nichols tells how gratitude helped reset and shape Martinez into a mindset that allowed her to earn a spot 3 days later on Team USA for the 1500-meter.
