After returning home for dinner with his children, the self-made billionaire CEO resumes his work at the office—that's just the nature of the job.

Peter Beck can attest to the fact that managing rocket launches into space demands constant vigilance.

Rocket Lab's founder and CEO, Beck, typically works long hours, especially during rocket launch periods, which makes it challenging to maintain a healthy work-life balance, according to a company spokesperson.

"Beck states that he is not winning any awards for his actions."

Over nearly two decades, Beck has transformed Rocket Lab from a startup with no college degree and few industry connections into a $12.93 billion business, as of Wednesday morning. The company's success has significantly contributed to Beck's net worth, estimated at $1.3 billion by Forbes last month.

To spend time with his family during his busiest workdays, Beck uses "workarounds," such as going home for dinner and then returning to the office or logging onto his computer from home to work late into the night.

"Beck confirms that he makes an effort to have dinner with his kids and acknowledges the importance of small gestures. When traveling overseas for work, he tries to schedule his trips during school holidays so that his family can join him."

Beck describes himself as a "chronic workaholic" and "paranoid about everything." He wakes up early each morning before 5 a.m. and spends most of his days at work worrying about his business and the technical aspects of each rocket his company launches into space.

"That's precisely what's required," Beck remarks. "That's simply the job."

Sacrificing for success

The stress of startup founders is compounded by the potential danger of each rocket launch in Beck's industry.

"Either it's accurate or it's international news, one of those two possibilities," says Beck. "Therefore, you should verify [everything] three or four times."

Beck, who works at Rocket Lab, has to be available at all hours for launches to occur. This means he sometimes has to sacrifice sleep and time with his family.

Jackie Bowie, a managing partner at financial risk management firm Chatham Financial, stated in CNBC's "My Biggest Lessons" last year that achieving a perfect balance between work and family life is generally unrealistic and can be a source of added stress for many working parents.

Bowie stated that if you're engaged in a task that's meaningful to you and brings you joy, you must accept that it may be challenging and require sacrifices.

Todd Graves, CEO of Raising Cane's, admitted to missing out on personal life while growing his business into a multibillion-dollar company, as he shared with CNBC Make It last month.

Graves' wife would bring their children to his office so they could play and eat dinner together before he returned to work. On vacations, Graves would wake up at 4:30 a.m. to work so he could spend leisure time with his family during everyone else's waking hours.

Graves stated that he is as busy as anyone he knows and travels as much as anyone he knows, but he can manage his schedule to prioritize his responsibilities to his children, family, and important friends.
