Here are timeless leadership lessons for all of us from: Warren Buffet, the most successful investor in history, whose wealth and power are balanced by self-deprecating wit, a modest lifestyle, and a well-earned reputation for honesty; Walt Disney, a salt-of-the-earth, hard-working artist who promoted family values but was also a tyrannical, micro-manager; Thomas Alva Edison, one of the most extraordinary innovators and entrepreneurs to ever live, who gave us the phonograph, the incandescent light, the Dictaphone, the mimeograph machine, the electric power-plant dynamo, motion pictures, and electric transmitters; Dwight Eisenhower, the thirty-fourth president of the United States, who confronted the most critical issues of the last century, working quietly behind the scenes while disarming friends and foes alike with his broad smile; Steve Jobs, the Apple co-founder and widely praised genius who dazzled the world with the revolutionary iMac, iPod, iPhone, and iPad; and Ray Kroc, who in building McDonald's into the world's biggest fast-food restaurant chain, adhered to virtues he considered indispensable for success - passion, persistence, simplicity, trust in frontline employees, and partnering with suppliers - plus smile, smile, smile.
