Over his 12-year career, three-time NBA All-Star Antoine Walker made more than $108 million. But just two years after retiring from the league, he'd lost it all.
"It was my darkest hour," Walker told CNBC, describing the day he filed for Chapter 7 bankruptcy in May 2010. At the time, he had about $4 million in assets and more than $12 million in debt.
His over-the-top spending combined with gambling losses and real estate investments that tanked in 2007 had left him with nothing.
Instead of burying his past under the rug, the NBA champion has made it his life's mission to educate others about financial responsibility. Walker is now a consultant for the Morgan Stanley Global Sports & Entertainment financial literacy initiative, which educates college and professional athletes on money management.
He shared some of the hardest money lessons he learned on his journey.
