EASY COME: As part of his tour promoting his cautionary documentary, Gone in an Instant, former Heat forward Antoine Walker this past week was interviewed by Bloomberg Television about how squandered $110 million over his career. "I want to teach people in general about having a lot of money," Walker said. "Different people come into wealth in different areas. I wanted to share my story. Going through bankruptcy, I had an opportunity to learn from my mistakes. . . . I want to tell my story so people can see it as a learning example." Walker spoke during the interview about winning the 2006 NBA championship with the Heat alongside Dwyane Wade and Shaquille O'Neal. "I felt like the world was mine at that age," he said. Walker said he also is establishing "a foundation for finance literacy."
