To say that Tony Robbins' life started off rocky would be an understatement.
But instead of letting these challenges hinder his success, they are a core part of what's fueled him to become a best-selling author, self-made millionaire and coach to the likes of former President Bill Clinton and hedge fund billionaire Paul Tudor Jones.
In a recent interview with CNBC, Robbins recalled getting chased out of the house with a knife by his mother when he was 17 and being physically abused by her as a child.
"If my mom had been the mother I thought I wanted, I wouldn't be as driven; I wouldn't be as hungry," he said. "I wouldn't have suffered, so I probably wouldn't have cared about other people's suffering as much as I do. And it made me obsessed with wanting to understand people and help create change."
Instead of feeling sorry for himself, the author of books such as "Money: Master the Game" and "Awaken the Giant Within" turned his early life setbacks into a springboard for growth.
"Our worst challenges, our worst problems, our worst failures — for those who don't give up — they give you insights," he said.
