As an athlete, I developed an ideal mindset for peak performance and used an arsenal of time-tested songs to fortify this alter ego and invincible state of mind. During my training and races it became obvious that even in really horrible weather conditions, or when I was physically suffering, that I could use music (and my imagination) to create a parallel universe that had little to do with reality. I used music to stay optimistic and see the glass as perpetually half-full while doing ultra-endurance races. You can use music as a tool when you work out or in your daily life the same way.
