Former President George W. Bush made his debut as a motivational speaker in Fort Worth, Texas on Monday, talking to an audience of 15,000 about his faith and optimism. Appearing at the "GET MOTIVATED!" seminar with the likes of Colin Powell, Rudy Giuliani and Terry Bradshaw, Bush appeared relaxed and comfortable on stage, speaking about his experiences in the White House and his life since he left office. A piece of his advice? "Popularity is fleeting... It's not real.” Estimates of Bush’s fee for the event have been placed around $100,000 (ticket prices ranged from $4.95 to $89). Bush received a warm response from the crowd and generally positive reviews from the seminar's participants. "He wasn't the best speaker," said one audience member, "but I was happy to see him!" He’s scheduled to deliver another motivational speech in San Antonio in November.
