Every month in Esquire, the captains of industry (Jack Welch) and the pop culture icons (Gene Simmons, Loretta Lynn), the leaders (Rudolph Giuliani) and the loudmouths (Don Rickles), reveal their philosophy of life in the What I've Learned column. Ten entertaining years' worth of their often-humorous, always thoughtful advice, along with stunning portrait photography, is gathered in this sharply designed compilation. The contributors include Muhammad Ali, Bill O'Reilly, Faye Dunaway, former Secretary of State Robert McNamara, Hugh Hefner, Elvis Costello, Lou Reed, Suge Knight, and Julia Child.
