People need to see the video of Serena Williams and Novak Djokovic dancing together after Wimbledon. It should be shown at schools, or at the end of particularly grim EastEnders episodes. During times of extreme global strife, the video should be beamed directly onto the surface of the moon. Because, no matter how hard you try, you will never see a more uplifting video so long as you live.
Why? Because it shows Williams and Djokovic wheeling around joyously, gleefully liberating themselves of the self-imposed pressure it takes to become best in the world at something?
