If You Push Hard Nonstop, You Will Not Become Superhuman. You Will Burn Out.

In his 14 year career as a venture capitalist at Intel, Charles Scott closed a series of noteworthy deals, including an investment in Atlanta-based JouleX, which was later acquired by Cisco, and Enjoyor, a China-based company that had a successful IPO in China. In 2011, he quit what was a successful corporate life that he enjoyed to be a professional adventurer.

Both careers require a fairly aggressive commitment to hard work. The secret to sustaining such elevated levels of effort, Scott has learned, is taking time off.

“What I have found is that ambitious people have the hardest time taking a friggin' vacation and just relaxing for a little bit. They are caught up, consumed by the goal itself, by the potential competitor who could take it away from you if you are too slow or lazy. They don’t honor recovery and the need to back off. But they absolutely honor the hard work,” Scott says. “This, by the way, is our culture. Our corporate culture is all about being Superman. We are supposed to have no flaws and no weaknesses.”

The most common running-rookie mistake is overtraining, he says, speaking to a roomful of attendees at the 3686 South entrepreneurship conference in Nashville last week. He knows a thing or two about running from personal experience. He’s run many thousands of miles, including more than 20 marathons, six Ironman Triathlons and other ultra marathons.

The 48 year old is also an avid fan of Mebrahtom "Meb" Keflezighi, an elite runner who has medaled in the Olympics and won both the New York City and Boston Marathons, the latter of which he won in 2014 at the ripe old age of 38. After earning the Boston Marathon medal, Keflezighi talked long about his hard work, but he also talked about his committment to rest and recovery. Scott noticed.

He started to recognize a dichotomy: the physical necessity of the human body to rest is largely understood and honored in the elite athletics world, but it’s categorically undermined in the American corporate world.

Scott works to get CEOs to talk about the importance of rest and recovery. Two weeks ago, he spoke at Uber. The way to get CEOs and entrepreneurs to think about rest, he says, is to educate them that it is the key to increased productivity. He also encourages those CEOs and leaders to have the conversation with their teams about the importance of rest and recovery.

The former VC suggests thinking about your time like marathoners think about training. “If it were possible, and the game was whoever trains the most number of hours wins, all the pros would run 23 hours a day. It does not work," he says. "Human physiology does not work this way. This has been learned from many many years and painful experimentation.”

In the same way that marathon runners take time off to let their muscles recover, so, too should people take breaks during their workday. Breaking your day, week, year and even entire career into periods of intense focus alternated with intense rest will lead to maximum productivity. Also, breaks allow creativity. Grinding away makes for exhausted brains that don’t have the space or energy for creativity.

Scott also suggests that everyone should take a 15-minute nap after lunch. “If you care mostly about optimal performance, you would nap after lunch,” he says.
