Bill Rancic is bringing his years of entrepreneurial success in the boardroom to the Us Weekly studio by sharing his greatest lessons learned and best advice going into the new year.

“I think, today, the biggest financial mistake people make is that they spend more than they can make, and that’s it,” Rancic, 53, exclusively told Us while discussing his new “Dollar Bill” podcast. “I always go back to what my father told me. ‘It’s not how much money you make, it’s how much money you save.’ So, you have to be a disciplined saver, even if it’s $10, $20, $50 a week — whatever it is, get in that habit. Don’t ever not do it, and you’ll be shocked at what happens in 20 or 30 years from now.”

Rancic is best known as the original winner of The Apprentice. After his reality television success in 2004, Rancic went on to launch a string of successful businesses, including the RPM restaurant chain with his wife, Giuliana Rancic. Bill’s latest venture is his “Dollar Bill” podcast, which further delves into the world of finance.

In terms of his savings tips, he gave Us further clarification on how to keep assets safe and secure.

Bill Rancic can’t get over how great Justin Bieber is with his and wife Giuliana Rancic‘s 11-year-old son, Duke. “[He’s the] greatest guy ever. The nicest guy. So good with Duke. I love that kid. He’s not a kid anymore, but [I] love him,” the entrepreneur, 53, exclusively told Us Weekly of Bieber, 30, on […]

“The money you save is really going to be up to you and [you should] find a good financial advisor,” Bill told Us. “[It should be] someone who can give you guidance on how you should invest it, but it definitely should be going to work for you.”

Bill also explained why individuals should “never sell anything unless [they] have to.”

“It depends on what it is,” he noted. “If it’s a depreciating asset, you should sell it. If it’s something like real estate, investment property [or] something that God isn’t making any more of, you want to keep it and pass it down from generation to generation, if you can.”

In fact, Bill believes that financial health is “just as important” as a person’s physical health, going on to add that he believes the two are actually linked.

“When you’re financially stressed, it causes stress on your body and if you look at a number one cause for divorce, it’s money,” he told Us. “Money, in many cases, is very troublesome for people and it causes them a lot of pain and suffering. So, you have to have good financial health in order to have a healthy life, a healthy marriage [or] a healthy family.”

The former Giuliana and Bill star also gave Us his three top tips for starting a new business.

“One is [to] embrace a term called ‘practical execution,’ which essentially means stop talking, start doing — actions speak louder than words,” Bill said. “Secondly, you have to be agile. You have to adapt, adjust, react, and if you’re not agile, you become extinct. And thirdly, it’s about risk. It’s about understanding risk, respecting risk, and converting risk into success.”
