Following in her father's footsteps, Serena Williams has devised an action plan for her future. Therefore, even if people are worried about or mocking her impending retirement, the athlete is hardly worried.

In an interview with Entertainment Tonight, the 40-year-old tennis player addressed reports that she's reaching the end of her illustrious career, revealing she's not fearful of it happening.

Though the 23-time Grand Slam champion's career isn't done just yet, the film King Richard's Richard taught her to be prepared for it. 'It's something she learned from her father Richard, she said. Her father is also the focus on the biographical film "King Richard."

"I am prepared for that day, I've been prepared for that day for over a decade," Williams said. "So, I've always -- if you've seen King Richard you know that my dad always said you got to prepare, so I've been prepared for that. You know, at the end of the day, I think it's really important to always have a plan and that's kind of what I did. I always had a plan," she added.

Since the birth of her first child, Olympia, 4, with husband Alexis Ohanian, Serena Williams has been juggling her tennis profession and personal life. This does not mean she's not looking forward to expanding her family.

Williams told ET that she's trying to figure out the best moment to further add more children to her family, despite the fact that her "balancing act" sometimes be "difficult."

"I definitely want to have more kids, it's just like, balance is key, you know, and just trying to find that balance," she added. "I don't know, it's always like, OK, are we ready? And I know the clock is ticking so I'm just like OK, I need to figure out when that's going to be, but hopefully soon when I will feel no pressure."

Williams however is sure that she will continue to play tennis until she retires.

Patrick Mouratoglou, Williams' coach since 2012, told PEOPLE in February of last year that he didn't see Williams retiring anytime soon.

"I don't think she will stop until she at least wins a Grand Slam, because she came back to win Grand Slams," Mouratoglou tells People magazine, referring to the tennis star's return after giving birth to daughter Olympia in 2017. "She doesn't quit," he added.

After her loss at the Australian Open in 2021, Williams was questioned by media about a possible retirement and ended a news conference early with obvious tears in her eyes. Mouratoglou explained that it is expected that Williams will feel intense emotions when the retirement day comes, as a result of her long-standing commitment to the game.

"The day she will retire, she will feel like she's giving an end to 40 years of a life," he said at the time.

"It's something that is difficult to measure for people," Mouratoglou further explained.

"That's why it's very sensitive. That's why it's very emotional for her. I completely get it," he added.

Margaret Court has the record for most Grand Slam singles championships won by a female tennis player. Williams is just one title way from tying with Court. Williams has three more major events left this year, so it's possible she'll catch up to Court or perhaps exceed her.
