Days after a quarterfinals loss in the 2010 French Open, Novak Djokovic told his coach, Marián Vajda, that he had decided to quit playing tennis. He was No. 3 in the world, a grand slam winner, and a favorite to win Wimbledon. After Djokovic said he was quitting, Vajda asked, “Why did you start playing this sport?” Vajda immediately sensed what the problem was: Djokovic was focusing too much on rankings, records, titles, and external expectations. As a result, Djokovic said, “I was mentally at one very messed up place.” As Djokovic thought about Vajda’s question, he thought about how many of his earliest childhood memories include his “most beloved toy”—a mini tennis racket and a soft foam ball. He started playing tennis, answering Vajda’s question, “because I just really loved holding that racket in my hand.” “Do you still love holding a racket in your hand?” Vajda asked. Djokovic thought about it for a few seconds, got excited, and said: “I do. I still love holding a racket in my hand. Whether it’s a grand slam final on center court or just playing around on a public court, I like playing for the sake of playing.” Vajda nodded, “Well that’s your source. That's what you need to tap into. Put aside rankings and what you want to achieve and what you think others are expecting of you.” Vajda then suggested that Djokovic take a few weeks off. Djokovic agreed that he would. But when he woke up the next morning, Djokovic was dying to hit tennis balls. He went to the courts to play for the sake of playing. “And I never looked back ever since that moment.” The following season, Djokovic enjoyed one of the greatest seasons in sports history. He won 43 straight matches. He won three Grand Slams, including his first Wimbledon title. And he finished the year as the number one player in the world. “I started to play freely,” he says of that season. “I became the kid that I was when I started playing.” Takeaway 1: There's a word for being like the kid who does something for the sake of doing it: Autotelic. From the Greek "auto" (self) & "telos" (end)—an Autotelic is "someone or something that has a purpose in, and not apart from, itself." As opposed to someone who focuses on rankings, records, titles, and external expectations—for an Autotelic... ”The work is the win,” as Ryan Holiday once told me. Since you control the effort more than the outcome, “Ultimately, you have to love doing it,” Ryan said. “You have to get to a place where doing the work is the win and everything else is extra.” Takeaway 2: When reading about Autotelics—people who describe their work as play, who simply seem to love what they do—a common mistake is to think that it’s all bliss all the time. One of my favorite Autotelics is the legendary skateboarder Rodney Mullen, who is in his 50s and still skateboards every day. “There are days,” Rodney said, “where you don’t want to go out. Or it hurts. Or you’re sore. Or you just suck—you're not making progress, and you feel defeated...But that's the nature of love—it's got hate in there, it's got pain in there. And that’s what draws you in, that's the magnetism.” At one point during the recent Wimbledon final, Djokovic angrily smashed and shattered his racket. And after losing the match, he admitted that it will take him a while to get over the loss. That’s the nature of love—it’s got hate in there, it’s got pain in there. - - - “I see people with talent, with all those things, but the one thing they don't have is just that love for doing it for the sake of it.” — Rodney Mullen Follow @bpoppenheimer for more content like this!
