"At a young age, I would write down all the tricks I wanted to learn," says Toby Miller, the pro snowboarder. A 2015 study led by psychologist Gail Matthews corroborates this goal-setting hierarchy: 43% of participants who merely thought about their goals achieved them (or were well on their way to success). Eric Potterat, PhD, is a performance psychologist who helped create the mental toughness curriculum used in Navy SEALs training. He spent 16 years at Google, partnering with executives to communicate the company's story to clients, partners, employees, and the public. He is the co-author of the books "How Google Works," "Trillion Dollar Coach," and most recently, "Learned Excellence."
