Serena's paycheck for winning this year's U.S. Open - $4million not only was the single largest paycheck in tennis history, but also put her over $60million in career prize earnings (most by a woman, 4th by any tennis player).
She is also, along with her sister Venus, the most-decorated tennis Olympian ever, with 4 gold medals; singles in 2012 and doubles in 2000, 2008, and 2012 (note that her golds are spread over 12 years!!).
She is a fashion designer, an author, a sometime-actor, and part-owner of the Miami Dolphins. She doesn't quit. She is a true renaissance woman and an American success story, and with many more chapters to be write. Happy Birthday, Serena.
