In fact, if Jack Dorsey could give his younger self one piece of advice, it would be to find a healthier work-life balance.
"When I was young I didn't understand the value of exercise or health and how that affected my intellect," he told Y Combinator. "I think it was useful for me to go to all the extremes to find the balance I have now, but I wish I focused more on being healthier in the past."
Today, the self-made billionaire maintains balance by sticking to a more structured schedule. "I look to build a lot of consistent routine," he said in a 2015 live Product Hunt Q&A. "Same thing every day."
Dorsey's routine involves waking up at 5 a.m., meditating for half an hour, and doing a seven-minute workout three times through — all before starting his workday.
"A healthier lifestyle ultimately makes me more creative and allows me to think more cohesively," he told Y Combinator.
Dorsey isn't the only successful person who values his health. According to author Thomas C. Corley, who spent five years studying rich people, many of the wealthiest people exercise consistently.
Science backs Corley's findings: Research suggests that working out can boost your memory, concentration and mental sharpness. Plus, numerous studies show that exercise is one of the most important habits you can develop to transform your life.
