According to a well-known anecdote, one day when he was $1 billion in debt, Trump pointed out a homeless man to his daughter and said, “See that bum? He has a billion dollars more than me.” The Guinness Book of Records lists him as having the biggest financial turnaround in history. “In the early 1990s, I owed billions of dollars and many people thought I was finished,” says Trump. “I refused to give in to the negative circumstances and I never lost faith in myself. I didn’t believe I was finished even when the newspapers were saying so. I refused to give up. Defeat is not in my vocabulary.”
