Richard Williams left no stone unturned to ensure that his daughters grew up to become professional tennis players. While both Venus and Serena Williams were supremely talented, it was Serena who always showed more potential. She also had a lot of hunger to improve her game.  Eventually, that hunger made her the most successful tennis player in the Open Era, as she won a whopping 23 Grand Slam titles during her career.

Recently, Rick Macci, who trained the sisters alongside their father and his friend, Richard Williams, shared a fascinating insight regarding Serena. The veteran tennis coach who also coached the likes of Maria Sharapova and Andy Roddick took to Twitter as he delved deep into the past.
