Serena Williams, the 23-time Grand Slam champion, has announced her intention to retire from tennis in order to focus on having another child and her business interests, presaging the end of her career that transcended sports. In her comment on her Instagram, Williams wasn’t clear on the timeline for her last match, but it could happen at the US Open. “There comes a time in life when we have to decide to move in a different direction. That time is always hard when you love something so much. “My goodness, I enjoy tennis, but now the countdown has begun,” Williams wrote on Instagram. One of the most accomplished and best athletes in history, Serena Williams, once wrote in an essay that she does not like the word “retirement.” Williams prefers to think of this stage of her life as evolving away from tennis toward other things that are important to her. She has to focus on being a mom, her spiritual goals, and finally discovering a different, but just as exciting Serena. She’s going to relish the remaining weeks of her career.
