Venus Williams remains focused on playing at the 2020 Olympics, admitting she has "no plans of stopping anytime soon".
The 37-year-old American has climbed back to number five in the world after an incredible 2017, albeit tinged with disappointment that she could not add to her grand slam collection after reaching the Australian Open and Wimbledon finals.
And she aims to continue on until the Tokyo Games, when she will be 40, having set herself that goal after the 2016 Olympics in Rio.
Williams lost in the opening rounds of the singles and doubles events but took silver alongside Rajeev Ram in the mixed doubles event to earn her fifth Olympic medal.
That was her fifth Olympic medal - tying the record of Kitty Godfree - providing Williams with more motivation to carry on.
"I have no plans of stopping anytime soon," she told Entrepreneur.
"It seems somehow that 2020 Tokyo is on the horizon. Isn’t that wild? I’m trying to stick around for that."
Williams also spoke about her busy off-court life as she runs her company EleVen and interior design firm V-Starr, while also studying to get a degree in design.
"Lately, I’ve been trying to figure out how to get the best out of it without going crazy," she added.
"That’s how your grades drop. I finally learned what school was about. It’s about getting the best out of it and using your time wisely.
"I maybe realised that too late. I always brought that tennis mentality to it, like, perfection, perfection, perfection."
