MONICA SELES
TENNIS
NET WORTH: $25 MILLION

You probably won’t see any teenagers nowadays who could accomplish the things she did on the field—using her unique skill set and unparalleled talent in playing the game. For those who aren’t in the loop, Monica Seles pretty much carried the whole competition on her back and won eight Grand Slam singles titles during her teenage years. She was born on December 2, 1973, in Novi Sad, Serbia. Her name is etched in history as the youngest competitor in the French Open that brought home the gold chip.

However, her success was cut short because of an on-court incident that took some good years from Monica’s career. We have to give her credit for showing that strong desire to play the game even after the incident, but she was never back to her championship form like it used to be back then.
