Trump called perseverance 'the second most important thing after love what you do.' He spoke with evident emotion about watching people over the years who were so close to succeeding but gave up just short of the finish line. He backed this with his own story of financial crisis. In 1990, Trump owed what some estimated at $9.2 billion. He joked that he 'slept well, but the banks didn't.' Through persistence, he rebuilt his company to become bigger and stronger than it had been in either the '80s or '90s, claiming the Guinness Book of Records listed it as the greatest personal financial comeback of all time. He closed this point with Abraham Lincoln's words: 'I will study and prepare and perhaps my chance will come.'
