Roger Federer is the greatest tennis player I have seen in a long life of watching and playing the game. He may have been overtaken by Djokovic as the winner of the most grand slams, which seems to be the public benchmark of the GOAT, but he will remain the greatest to me.

His greatness is not just on the court, where everything seemed effortless. It extends to his demeanour and humility off the court.

In a recent commencement speech at Dartmouth College, he gave the graduates a critical piece of wisdom that applies widely to life:

“Perfection is impossible. In the 1526 singles matches I played in my career, I won almost 80% of those matches.

Now, I have a question for you.

What percentage of points do you think I won in those matches?

Only 54%.

In other words, even top-ranked tennis players win barely more than half of the points they play. When you lose every second point on average, you learn not to dwell on every shot.

You teach yourself to think, okay, I double-faulted … it’s only a point. Okay, I came to the net, then I got passed again; it’s only a point. Even a great shot, an overhead backhand smash that ends up on ESPN’s top 10 playlist. That, too, is just a point.

And here’s why I’m telling you this. When you’re playing a point, it has to be the most important thing in the world, and it is. But when it’s behind you, It’s behind you. This mindset is really crucial because it frees you to fully commit to the next point and the next point after that, with intensity, clarity, and focus’.

Those words resonated with me.

They resonated, not just because I lose way more than 50% of the points I play these days, and must accommodate that in my competitive brain, but because it applies to the way we all should live our lives.

It certainly applies to those I work with, where an obsession with the past often clouds the next move, and the one after that.

We need to understand why what we did worked out differently to the plan, and learn to adjust both on the run, and over time as we alter the mechanics and drivers of activity. Beyond that, the past is irrelevant. It is the past, unchangeable, immutable.

By contrast, what we do with the lessons of the past is crucial.
