Serena Williams insists retirement is not on her agenda as the 34-year-old targets a sixth Olympic gold medal.
The USA superstar arrives in Rio after claiming a seventh Wimbledon title to pull level with Steffi Graf's Open era record of 22 majors.
But even if she secures a second successive Olympics singles gold and fourth in the women's doubles alongside her sister Venus, she still has no intention of hanging up her racquet.
"I love what I do every day and enjoy being on the court. I enjoy competing," said Williams.
"I just don't see a time when I say I don't want to do this anymore. I always give my maximum and that's what I bring to the court."
Williams won her first Olympic singles gold in London four years ago and then doubled up with Venus.
The sisters had also won doubles gold in Sydney in 2000 and Beijing eight years later, with the only blot on her Games record the 2004 Olympics in Athens, which she missed with a knee injury.
Williams said she still remembers her maiden gold medal alongside her older sister in 2000 when she was just 18.
"We all dream of the Grand Slams and winning them, but the Olympics are different," said Williams, who will be top seed in Thursday's draw for Rio.
"The first gold medal I won was something I appreciated more than a lot of my trophies.
"It's really great to have another opportunity to win the title. Having won it already definitely takes the pressure off."
The Olympic tennis tournament, which starts on Saturday, has been hit by a number of high-profile pull-outs.
Five of the top 10 in the men's rankings, including Roger Federer, as well as leading women's stars such as Victoria Azarenka, Maria Sharapova, Simona Halep and Belinda Bencic, are missing.
Also out are Williams' fellow Americans John Isner and Sam Querrey, as well as defending men's doubles champions Mike and Bob Bryan.
However, 36-year-old Venus insists missing the Olympics was never an option. She said: "We felt we couldn't say no. We wanted to be here."
