Book excerpt: When he was young, consultant Bill Treasurer feared heights. He overcame his fear and became a high-diving champion. Every day for seven years, Treasurer would climb to the top of a 100-foot tower (as tall as a 10-story building). From there, at a speed of more than 50 miles per hour, he'd dive head-first into a 10-foot deep pool. He became the captain of the US High Diving Team. Now, he teaches managers how to be brave and how to imbue their workers with courage. In this tenth-anniversary edition of his bestseller on building courage in the workplace, Treasurer jokes that he hopes to enroll his readers in the "Fraternal Order of Courageous Managers."
