“In the 1,526 singles matches I played in my career, I won almost 80 percent of those matches,” Mr. Federer said. “Now, I have a question for all of you. What percentage of the points do you think I won in those matches?”
The answer was 54 percent.
“In other words,” he said, “even top-ranked tennis players win barely more than half of the points they play.”
He went on, “The truth is, whatever game you play in life, sometimes you’re going to lose. A point, a match, a season, a job.”
