Djokovic was asked what it cost him to be No. 1 for so long and to continue playing at the highest level even at 37 years old.

“Grigor gave part of the answer to this question. It takes dedication and discipline to be at the required physical and psychological level, as well as motivation and persistence. There are multiple factors. There is no single winning formula or universal recipe for success. You have to gain an understanding of yourself and get to know your body."

'I am already 37 years old, which is a serious age for a professional tennis player. I’ve been playing for almost 20 years and my body is feeling it more and more. This is exactly why l'm playing less often and becoming more picky about my schedule. As I said, motivation is also a must. Everyone wants to be #1 and win Grand Slam titles, so the competition is always very strong. In professional tennis you have to constantly adapt to different conditions and sometimes the body suffers from this. You have to be obsessed, but in a good way. Going to bed and getting up thinking how to get better. This applies to an even greater extent in individual sports, since in them there is no one to hide behind. There are a lot of hungry wolves, young players challenging the veterans, but we are still strong."

At the Paris Olympics, Djokovic won the gold medal in singles, the only honor that had so far eluded him. The Serbian shared how this affected his motivation.

“For the first time in my career, I have no long-term plans. I'm living for the moment and we'll see what happens. Today I will play in Sofia, then in China, and then at a demonstration tournament in Saudi Arabia. After that, | don't know. We'll see how I feel and judge. Family life is very important to me. I want to be with my wife and children, to be a part of their everyday life - something I haven't been able to do for many years. I have to balance things out, so we'll see. I still want to chase titles and records, but at the same time I have to be sensible and prioritize certain tournaments over others.”
