I have always been fascinated by how wealthy people approach money.

25 billionaires and more than 100 self-made millionaires have been interviewed by me as a CEO and host of "We Study Billionaires".

I don't know what I've learned from them. Rich people don't have a "lottery mindset" or the belief that there's a shortcut to instant wealth.

Three habits they share can be adopted by anyone.

The stock market is treated like a puzzle by the most successful people.

I talked to Howard Marks about how he weathered the Great Recession and the early days of the Pandemic.

He said he focused on the data and potential opportunities instead of on the risks or downsides.

During the 2008 financial crisis, he made a successful bet on distressed corporate debt using this approach.

Marks suggests that you take emotions out of the equation and look for ways to make the situation work for you.

Warren Buffet invests in businesses that have the potential to grow in value decades into the future, no matter what the stock price is.

Many billionaires have admiration for the way in which Buffet approaches his job. Brian Chesky talked about his lunch with Jeff Bezos and Warren Buffet at the conference.

Bezos recalled one of his first meetings with Buffet, in which he asked him, "Your investing thesis is so simple." Isn't everyone copying you?

No one wants to make a lot of money quickly.

The co- founder of Carlyle Group was interviewed by me. He is a philanthropist who serves as a board chairman. He is also the host of a PBS show.

He noted all the things he doesn't do when I inquired about how he gets so much done. He doesn't like the things that drain his time.

The power of saying no is agreed upon by billionaire Jesse Itzler. One of the world's largest private jet card companies, a partner in Zico Coconut Water, and an owner of the NBA's Atlanta Hawks are all owned by Itzler.

He told me that it was a good time to say "yes" in your 20s and 30s. You want to build. It's a good time to say "no" and take full control of your time.

His tip for saying no is to follow up with an amazing thing. Pick up a bill if you want to send a dessert. You don't have to be out of the game if you choose not to.

The co- founder and CEO of Better Booch is also the host of the show "We Study Billionaires". You can follow him on both social networking sites.

Don't miss anything.
