In a jaw-dropping revelation, Serena Williams opens up about the personal sacrifices behind her unstoppable rise to the top. Fame, fortune, and trophies? She’s paid in something priceless… and now, she’s telling all.

The WYN Beauty creator told PEOPLE that the greatest costs of her career and overarching success weren’t even financial

Serena Williams, 43, revealed in an exclusive chat with PEOPLE why success is “very expensive” during a special appearance at the WYN Beauty x Shopify pop-up event in Los Angeles on Friday, April 11.

Yeah, it definitely costs a lot,” explains the tennis legend and WYN Beauty creator. “I’m here [in California] without my kids, and that’s a big cost for me because I spend a lot of time with my children, and they’re very attached to me, which a part of me loves. So, it’s always some cost.”

Williams added that the greatest costs of her athletic career and overarching success weren’t even financial. “My whole life I’ve had to kind of weigh, like, ‘If I wanna win a championship, well what is that going to cost me?’ ” Williams says. “It’s going to cost me time with my family, it’s going to cost me friends, it’s going to cost me relationships. And they’re very expensive. You have to decide if it’s worth it for you.”

Williams shares two daughters, Alexis Olympia, 7, and Adira River, 1, with her husband Alexis Ohanian, whom she married in November 2017.

The Compton-raised multi-hyphenate, who lives in Florida with her family, was at the event to celebrate the one-year anniversary of WYN Beauty, which she founded and launched in April 2024.

While Williams has excelled in nearly every arena she’s entered — both on and off the court — she reveals that she has no plans to take on another large business venture.

“I’m done!” Williams says with a chuckle. “I’m not launching anything else like this. I just am happy doing WYN Beauty. And I’m happy being a mom and I’m happy with my venture company, and that’s a lot. We’re good!”
