Warren Buffett steps down as Berkshire Hathaway chairman

Warren Buffett, Richard Branson, and Microsoft CEO Satya Nadella share a belief that their hobbies contribute to their success. Nadella says cricket taught him teamwork and leadership lessons. Branson finds physical activities expand his day and make him more productive. Buffett champions bridge as the best brain exercise, as each turn demands adaptation to new information.

However, conventional wisdom suggests success demands total focus, with no distractions. Yet, a study showed entrepreneurs who kept day jobs had 33% lower failure rates than all-in entrepreneurs. Another study on athletes found world-class athletes typically played various sports before specializing, suggesting a diverse background boosts athletic prowess.

Research also indicates Nobel Prize-winning scientists were three times more likely to have outside interests like singing, acting, or woodworking. This suggests hobbies can boost creativity and innovation.

For entrepreneurs, a hobby should be low in similarity to their profession to avoid burnout. A hobby that's too similar to your work can drain self-efficacy and identity. Instead, a hobby that's dissimilar and low-stakes can provide a mental break and increase self-belief. Epstein notes examples of successful individuals, like a world-class runner who took up knitting and an Olympic skier who built houses, who found hobbies that took their minds off their careers. Hence, a hobby could enhance overall performance and longevity in one's business.
