This story is part of CNBC Make It’s The Moment series, where highly successful people reveal the critical moment that changed the trajectory of their lives and careers, discussing what drove them to make the leap into the unknown.

Jay Chaudhry never thought he’d run a business, amass a fortune or help popularize an entire industry. Not growing up in rural India, not upon moving to the U.S. in 1980 to study engineering and marketing, not even after landing jobs at tech giants IBM and Unisys.

“I have no background of entrepreneurship in my family of small-scale farmers. So if you asked me, ‘Did I ever think about becoming an entrepreneur in my childhood [or] early years of my career?’ Not really,” Chaudhry, the billionaire founder and CEO of cloud security company Zscaler, tells CNBC Make It.

It took Silicon Valley’s dot-com boom — the wild success stories of tech startups like Netscape — to get Chaudhry thinking in 1996, “Why shouldn’t I start a company?” He made the rash decision to quit his job as an executive at Atlanta-based tech company IQ Software, and his wife Jyoti quit her job as a systems analyst at telecommunications giant BellSouth.

Together, they plunged their life savings — roughly $500,000 — into SecureIT, a cybersecurity software startup they co-founded in 1997. At the time, “maybe less than 5% of Fortune 500 companies had firewalls,” Chaudhry says. “Within 18 months, we had deployed firewalls in about 50% of [the] Fortune 500.”

His timing was perfect: In 1998, Chaudhry sold SecureIT to VeriSign in an all-stock deal worth nearly $70 million. Over the ensuing decade, the husband-and-wife duo founded two more cybersecurity companies and an e-commerce business, each of which got acquired.

By 2007, they were already wealthy entrepreneurs, and Chaudhry — who gets “bored” without something to work on — decided it was time to launch “one big company and put 200% focus on that,” he says.

That company was Zscaler, which aimed to help companies transition away from outdated firewalls and into the cloud era. The couple invested $50 million of their own money, says Chaudhry. Today, it brings in $1.6 billion in annual revenue and has a market value of roughly $30 billion.

Chaudhry’s own net worth is estimated at $11.5 billion by Forbes.

Here, Chaudhry talks about putting his family’s savings on the line to follow his gut, how his upbringing influenced his relationship with money and the advice he’d give someone who wants to quit their job to start a business.

CNBC Make It: What prompted you to stake your entire life’s savings on a startup idea — in an industry that didn’t really exist yet?

Chaudhry: This thing happened because I love to read and I love technology.

In 1996, Netscape had just launched and gone public, and I was fascinated by it. I said, “If [Netscape co-founder] Marc Andreessen could start a company — he was a young guy [right] out of college — why shouldn’t I start a company?”

My wife and I talked a few times, and the more we thought about it, the more conviction we got around it: [Netscape’s web browser] is the way to access information, and it should become popular. But if every company is connected to the internet, that means there will be security risks.

That was my simple thinking. There was no IDC or Gartner study about the market size. It was largely based on what the gut told us.

A gut feeling is one thing. Betting every dollar to your name is another.

It started out with us saying, “Let’s go get venture capital funding.” I had no experience raising funds, and I realized soon that it wasn’t that easy. This was [1996], Atlanta was not a VC mecca and we kept hearing, “Hey, you don’t have any experience.”

We were disappointed, but our conviction was building, which led to me saying, “Why don’t we put our life-savings on the line?”

I didn’t know anything. So, I really didn’t know how big the risk was. I couldn’t quantify it.

How did you make peace with that risk?

After talking back and forth, we asked each other, “What’s the worst thing that can happen?” The company could shut down, we’d lose all of our savings.

The next question was, “Can we find jobs?” There was lots of confidence that we could.

I never had money in my early childhood, so there was never a notion that I must buy A and B and C. Our lifestyle was pretty simple. Our house in Alpharetta, Georgia, was $200,000 — a nice, typical middle-class house at that time — and we didn’t have any fancy cars or fancy payments.

Our only child at that time was going to a public school. There wasn’t a lot of overhead. We said, “Let’s take a chance.”

When a bet pays off, does that success make you more confident to take on bigger risks? Were any of your other ventures as risky as that first one?

The [financial] risk of SecureIT was, like, 1,000 times more than the risk of Zscaler. The amount I invested in Zscaler was a small fraction of my net worth.

But Zscaler was much harder. I put more money in it than all the others combined. I took bigger bets. I hired people more quickly to solve some very hard problems. I wanted to do something big, something lasting.

We were trying to solve a problem that was futuristic. Will it be successful or not? Will the market take off or not? That was all unknown.

So if you asked me the chances of success of Zscaler, there was a much higher risk. Because, with SecureIT, it was fairly obvious that as you connect to the internet, you need firewalls.

What’s your best advice for someone who’s thinking about quitting their job to start their own business?

First, build conviction by learning more about what you want to do. Don’t just do some of the cursory work.

Second, start by putting in your own money. That actually is part of testing your conviction. If you really have conviction, you’ll take a chance on yourself. That also means you’ve done some serious homework, you’re ready, you’re committed.

You can also make decisions the way you want to make decisions. If Zscaler was largely owned by VCs, they probably could have shut it down. It took us a few years to really start getting traction in the market, and VCs can write you off and move on. They say, “It’s one of my 20 investments.”

When you put in your own money, this is the only business you have.

You have to earn more than $1 million annually to be among the top 1% of earners in the richest U.S. states and Washington, D.C., a new GOBankingRates study reveals.

In D.C., you’re in the top 1% if you make $1,250,029 or more — the highest threshold in the U.S. That’s followed by five states where you also need to come in over the $1 million mark to be a top earner: Connecticut, Massachusetts, California, Washington and New Jersey.

The 1% thresholds are based on individual tax return data processed by the Internal Revenue Service in 2022, which has been adjusted by GOBankingRates to reflect 2024 dollar values. Here’s a look at where the 1% earn the most, based on that metric:

1. Washington, D.C.: $1,250,029
2. Connecticut: $1,192,947
3. Massachusetts: $1,152,992
4. California: $1,072,248
5. Washington: $1,024,599
6. New Jersey: $1,010,101
7. New York: $999,747
8. Colorado: $896,273
9. Florida: $882,302
10. Wyoming $872,896

One reason that Washington, D.C. has a higher threshold compared with states like California and New York is that it has a smaller population with a larger concentration of high-income earners. Many of the highest paid D.C. professionals are in the government sector, which includes senior officials, lobbyists and lawyers.

Connecticut also has a smaller population compared with most states. The state’s largest industry is financial services, and it is home to wealthy hedge funds and investment firms that tend to pay high salaries.

Massachusetts ranks third, largely due to an array of lucrative industries with high-paying specialized jobs, including financial services, education, technology and health care.

In contrast, West Virginia has the lowest income threshold for the top 1% of earners, starting at $435,302. Nationwide, the 1% income threshold is a median of $707,296.

Below are the thresholds for each state, in alphabetical order:

• Alabama: $577,017
• Alaska: $642,707
• Arizona: $713,264
• Arkansas: $550,469
• California: $1,072,248
• Colorado: $896,273
• Connecticut: $1,192,947
• Delaware: $640,330
• Florida: $882,302
• Georgia: $725,284
• Hawaii: $631,383
• Idaho: $728,859

One key trait separates the best CEOs from all others, according to JPMorgan Chase CEO Jamie Dimon.

While some leaders can get complacent in their lofty roles, a great CEO prioritizes learning, inquisitive conversations and taking genuine interest in other people’s points of view, Dimon, 68, told LinkedIn’s “This is Working” video series last week.

“I think leaders have to get out [from behind their desks],” Dimon said. “They have to get out all the time. They have to be curious, ask a million questions. They’re learning from competitors, they’re learning from clients.”

One of Dimon’s top priorities for himself is meeting with clients and competitors — so he can ask questions and get firsthand accounts about where his company is excelling or doing poorly, he said.

“I always tell a client, ‘When you complain to us, you’re doing us a favor. If we’re torturing you, we’re probably torturing another 10,000 [or] 100,000 people,’” Dimon said. “I think CEOs, any business leader, who can’t get out [or is] too busy, they’re making a huge mistake.”

Dimon isn’t the only CEO who values inquiring minds in the workplace: The trait separates highly successful employees and leaders from their peers, according to Amazon boss Andy Jassy. 

“You have to be ravenous and hungry to find ways to learn,” Jassy said last week in a video published by Amazon, about the company’s list of 16 leadership principles. The biggest difference between people with successful careers and those who remain “stagnant” is a constant, humble drive for knowledge and self-improvement, he added.

“For some people, at a certain point, they find it too threatening or too difficult to keep learning,” said Jassy. “The second you think there’s little left for you to learn is the second that you are unwinding as an individual and as a learning professional.”

Curiosity and desire to learn can take you further in your career than your technical skills, LinkedIn vice president and workforce expert Aneesh Raman told CNBC Make It in March. The two traits are especially beneficial for young professionals, helping them stand out in the hiring market and reframe setbacks as learning opportunities, he said.

″[A growth mindset] is the new degree, the way that you’ve been looking for a Harvard degree,” said Raman.

To strengthen your inquisitiveness, try dedicating 20 to 30 minutes each day to learning something new, TedX speaker and organizational psychologist Tomas Chamorro-Premuzic wrote in the Harvard Business Review last year. You could research a subject you’ve always been interested in, set up a coffee chat to learn more about a colleague or read a challenging book about an unfamiliar subject. 

Ask yourself questions like, “What area do I want to be an expert in?” and “What topics could I spend all day thinking about?” Chamorro-Premuzic wrote.

Continuing to learn and explore, in both familiar and new areas of interest, helps people avoid “complacency” and build the “heart and grit” they need to advance their careers, said Dimon.

“If you don’t have an accurate assessment of the real world out there, what’s changing, what the ideas are, you will eventually fail,” he said.

Bridgit Mendler’s path from Disney Channel star to space startup CEO started with — quite literally — an accident.

The 31-year-old is the CEO and co-founder of Northwood Space, a company based in El Segundo, California that aims to mass-produce ground stations — otherwise known as the antennae that communicate with space satellites. It’s a far cry from her youth spent as a child actor and recording artist, known for roles in Disney Channel shows and films like “Good Luck Charlie” and “Lemonade Mouth.”

“While everybody else was making their sourdough starters [during the Covid-19 pandemic], we were building antennas out of random crap we could find at Home Depot … and receiving data from [National Oceanic and Atmospheric Administration] satellites,” Mendler told CNBC on Monday while announcing her startup.

Mendler was still acting on screen as recently as 2019 — but her new career path began more than a decade ago, when she unintentionally marked a box on her University of Southern California college application.

“I’m studying anthropology,” Mendler told ABC’s “Jimmy Kimmel Live” in 2015. “But it was an accident … I was doing the application all on my own. I think I didn’t really understand how it worked. I put down like five different things that I would potentially want to be in as a major, and I got my acceptance letter, and it’s like, ‘You’re in anthropology.’”

The educational field resonated with her: Despite dropping out of USC in 2016, she later pursued a master’s degree in humanity and technology from the Massachusetts Institute of Technology, according to her LinkedIn profile.

She’s now working to complete PhD and juris doctor programs, she wrote in a post on social media platform X on March 7, after this story was first published. According to her LinkedIn profile, those programs are respectively at the MIT Media Lab and Harvard Law School, where she said she served as co-president of the Harvard Space Law Society between 2022 and 2023.

“I have two engineer parents,” Mendler said at an Atlantic Live event in 2018. “My mom’s an architect and my dad designs car engines. So there was a lot of math-y science-y talk when I was a kid.”

Her off-screen experiences lend credence to Northwood, which she co-founded with her husband, CTO Griffin Cleverly, and head of software Shaurya Luthra — whom she referred to as her “two favorite ground nerds” in a LinkedIn post.

The startup is already on the radar of several venture capital investors, raking in $6.3 million in initial funding from firms like Founders Fund, Andreessen Horowitz, Also Capital and Humba Ventures.

Some of Northwood’s early employees have track records at Elon Musk’s SpaceX, Peter Thiel’s Palantir Technologies and aerospace technology company Northrop Grumman, Mendler noted in her LinkedIn post.

“At Northwood, we’re rethinking infrastructure for satellite backhaul from the ground up. We have our sights on building a data highway between earth and space,” she wrote, adding: “We have a lot of work ahead of us but that’s the fun part.

Correction: This story has been updated to reflect that Mendler dropped out of USC in 2016, and include her statement on social media platform X that she has not yet completed her PhD or juris doctor studies.

When it comes to luxury spending, billionaire Mark Cuban draws the line at yachts, butlers and house cleaning services.

“I just try to be the same person, I mean, as I was when I was poor, middle and rich,” Cuban, 65, told “The Really Good Podcast” on Thursday. “The whole idea of like, get a yacht … it’s just not what I would do.”

Cuban, a serial entrepreneur and startup investor, has a net worth of $5.1 billion, according to Forbes. He’s not opposed to big-ticket purchases: He spent $13 million on a 24,000-square-foot Dallas mansion and $40 million for a private Gulfstream V business jet in 1999, shortly after becoming a billionaire. The following year, he bought the NBA’s Dallas Mavericks for $285 million.

Rather, Cuban’s decision to not pay for certain services is less about frugality and more about his desire for a private life. His family usually does their own chores, like washing clothes and cooking meals, he noted.

“I like the privacy,” Cuban said. “I’ve been around people who hire somebody to do everything for them, and that’s just, like, no privacy.”

Similarly, Cuban didn’t feel the need to make new friends upon entering a new tax bracket, he said: “Most of my friends are guys that I moved to Dallas with or friends in Indiana from school. We still tell the same stupid ass stories and do the same stupid s—, and you know, that’s good.”

In January, Cuban told CBS’s “Sunday Morning” that he’d worked hard to keep his wealth from changing his personality, and that he’d be just as happy with 1% of his net worth. Later in the interview, a group of Cuban’s childhood friends confirmed it.

“Little more full of it, but not that much more full of it,” Jerry Katz, one of those friends, said. “But still the same guy.”

That isn’t the case for most people: Typically, the wealthier you feel, the worse you behave, according to Paul Piff, an associate professor of psychological science at the University of California, Irvine.

“As a person’s levels of wealth increase, their feelings of compassion and empathy go down, and their feelings of entitlement, of deservingness and their ideology of self-interest increases,” Piff said in a 2013 TED Talk.

When that happens, small reality checks can help you get back on track, Piff added: “Small nudges in certain directions can restore levels of egalitarianism and empathy.”

Cuban now owns three houses, and refers to a couple of his private jets as his “best toys,” he said on the podcast. Buying a private jet “was my all-time goal, because the asset I value the most is time, and that bought me time,” he told Money in 2017.

Still, Cuban wants to remain the same person he was when he was “broke,” he said on the podcast.

“When I was broke, I had a blast,” said Cuban. “I loved my life … I was still having fun.”
