Despite the ringing of two stray cell phones disrupting the quiet, all eyes and ears were glued, almost reverently, on New York City's former Mayor Rudy Guiliani at INTERPHEX when he presented the day's keynote address. First, he thanked the audience for providing the therapeutic options that allowed him to successfully defeat prostate cancer awhile back. Next came his imitation of James Gandolfini in the hit TV show "The Sopranos," as he reminisced about his duties as NYC's former chief prosecutor. Once he had our full attention, close to 1,000 of us, he shared what he felt are the most valuable leadership attributes and how they will successfully get you through challenging and uncertain times.
