23 Grand Slams later, Serena Williams reveals what makes her the most proud in her career

American tennis legend Serena Williams has achieved almost everything a tennis player could ask for. Twenty-three Grand Slam titles, four Olympic gold medals, three hundred nineteen weeks as the world No. 1 singles player, and whatnot. But none of these achievements make the 42-year-old the most proud in her career.

When asked about the thing she is most proud of in her career, Williams was quick to talk about her perseverance. The 42-year-old said that she is proud of herself for being able to live through the thick and thin. Williams said that this trait of athletes often gets overlooked but she is proud of her perseverance.
