Regarding these accompanying photos, which encourage me through the positive spirit these men have exhibited throughout their lives, the Ronald Reagan picture was taken after he left office but before he became ill. We shared a platform in Charlotte, North Carolina, where we gave our respective talks to more than 25,000 people.

The photo with Lt. Col. Oliver North (retired) is more recent and was taken in Grand Cayman. Colonel North (or "Ollie," as he's known) visits Grand Cayman from time to time. He is an extraordinary leader.

The bottom photo shows me and famed tennis coach Nick Bollettieri. I am currently writing Nick's authorized biography, tentatively titled

The Bollettieri Way.
