For over 30 years, Netflix co-founder has maintained this weekly ritual to ensure his success.

Marc Randolph, co-founder of Netflix, takes the most pride in something other than contributing to the launch of the streaming giant.

The 66-year-old is most proud of maintaining a balance between his career success and a fulfilling personal and family life, as he shared in a recent social media post on platform X. Randolph attributes this balance largely to a weekly ritual: Tuesday night dates with his wife.

"For over 30 years, I consistently left work at 5 p.m. on Tuesdays to spend the evening with my best friend, regardless of the weather."

Randolph wrote in a LinkedIn post last year that working within set boundaries helped him prioritize his work and make time for his family and personal interests.

"Randolph stated that he is most proud of his ability to start companies while maintaining a long-term marriage and raising children, allowing his kids to grow up knowing him and enabling him to pursue other passions in his life."

Experts suggest that setting boundaries between work and personal life can prevent burnout, which may have contributed to Randolph's professional success.

Balancing work and life is easier said than done, as even Randolph has struggled to adhere to his own rule, as he admitted in a February Substack post.

The reality of work-life balance

During his busiest periods, Randolph often wrote on Substack instead of physically going home to work on companies or large projects.

In 1997, while starting Netflix with Reed Hastings, he broke his own rule by going home to "scarf down dinner with the family" before returning to work.

""Few individuals can attain equilibrium daily, including myself," he stated."

Randolph struggled to adhere to his Tuesday night routines, so he attempted to compensate by spending more time with his family and resting in other ways. After Netflix launched, he took a break. Currently, he is attempting to condense his week by scheduling meetings on the same two days, dedicating one day to "deep work" and spending more time with his family on other days, as he wrote.

A last-minute work emergency can disrupt a strict schedule, but when things are running smoothly, I take advantage of it by earning myself a four-day weekend and make sure I'm fully decompressed, as Randolph wrote.

Mark Cuban, a billionaire entrepreneur and startup investor, agreed with Randolph's statement at a SXSW panel in March, stating that there are times in your career when you may have to sacrifice date night in order to successfully launch a business.

"As an entrepreneur, you must accept the lack of work-life balance because there's always someone else trying to outdo you and take your place."

Randolph believes that striving for balance is important, but it's okay to occasionally fall short. It's impossible to do everything perfectly every day, including exercising, meditating, hustling, focusing, socializing, and delivering great presentations, while also eating a healthy diet and getting enough sleep.

"Randolph stated that in reality, it is not possible to do that every day. He added, "The key is to determine your own method of achieving balance, regardless of your schedule.""
