WIMBLEDON, England — The focus has understandably been on Serena Williams’s comeback this season.

She was the tennis superstar returning from childbirth with Margaret Court’s record of 24 Grand Slam singles titles in her sights.

She was the one showing the way, at age 36, for working mothers and older athletes to keep striving for more.

But Angelique Kerber’s comeback has some lessons for the wider world as well: about persistence, about overcoming weaknesses by developing your strengths, and about sticking to your very fine game plan in a Wimbledon final against an opponent of superior power and experience.

Kerber struggled last season after winning two Grand Slam titles in 2016 and moving up to the No. 1 ranking. But at 30, she has made an emphatic return to the top, reaching the semifinals of the Australian Open in January and then winning the trophy she has long wanted most by defeating Williams, 6-3, 6-3, on Saturday.
