When Michael Lewis graduated from Princeton with a degree in art history, he decided he wanted to be an author even though he had never published a word in his life. One night at a dinner he sat next to the wife of an executive at Salomon Brothers, an investment bank. She pressed her husband to give Lewis a job, and that job gave him the subject for his first book, Liar’s Poke, which sold millions of copies when he was just 28 years old. Speaking to graduates at Princeton this year, Lewis said that successful people take credit for their own success, not realizing how much of it is due to luck—like sitting next to someone at a dinner party. Lewis said that “with luck comes obligation. You owe a debt, and not just to your Gods. You owe a debt to the unlucky” (www.Princeton.edu).
