With eight-figure yearly earnings and a reported net worth of $500 million, Magic Johnson should not have any huge regrets when it comes to making bad financial decisions. But during a recent appearance on The Ellen DeGeneres Show, Magic admitted to one costly error in judgment when he was leaving Michigan State to go into the 1979 NBA Draft. "When I first came out of college, all the shoe companies came after me," he said. "And there was this guy, Phil Knight, who just started had Nike."

"All the other companies offered me money, but they (Nike) couldn't offer me money because they just started," Magic said. "So he said something [about] stocks—'I'm gonna give you a lot of stocks.' I didn't know nothing about stocks. I'm from the inner city, we don't know about stocks, you know, at the time." 

"Boy, did I make a mistake," Johnson admits. "I'm still kicking myself. Every time I'm in a Nike store, I get mad. I could've been making money off of everybody buying Nikes right now."
