You Don't Want to Be a Renter Nation.

In 2008, Grant Cardone almost went broke. He was so disgusted with himself that he swore to his wife: Next time this happens, we'll have 10 times the debt. That's where the 10 X rule came from. The mantra of 2008, nine and 10 was too big to fail. I put my family at risk. But third, I couldn't take advantage of the opportunity. Like, I wasn't broke. I was broken. My courage was like literally sucked out of me. So then I couldn't pull the trigger."
