If there ever were a rags-to-riches story, this is definitely it. John Paul DeJoria is a billionaire (he's worth about $4 billion) today but before making it big, the co-founder of Paul Mitchell Systems was homeless. Twice.

DeJoria grew up in a poor single parent household and got his first job at the age of 9, selling Christmas cards door-to-door. In his early 20s, things got so bad he didn't have a place to live.

DeJoria found himself homeless again just as he was starting up Paul Mitchell Systems in 1980 (with a mere $700). He was in the middle of a split with his wife at the time and ended up sleeping in his car for a few weeks.

Despite these challenges, John Paul DeJoria said on "Off the Cuff" that his mom instilled a solid work ethic in him, letting him know he "could do whatever you want to do, never give up… keep on working, keep on going forward…".

Jerry Storch can easily imagine what he would be doing if he wasn't the chairman and CEO of Toys 'R Us, the world's largest toy retailer. He would be writing, writing, and writing some more, he said.

"It's always been a struggle in life trying to [think], do I write? Do I do a 'real' job?" he said on "Off The Cuff", "I've sketched some things down over the last 20 years and I'm ready to get going."

But that project may have to wait a little longer. At the moment, Storch is working hard to strengthen Toys 'R' Us position as both a toy and baby products authority.
