Maria Sharapova
“Instead of letting that depress me, I became more quietly determined and mentally tough. I learnt how to take care of myself. I never thought of quitting because I knew what I wanted. When you come from nothing and you have nothing, then it makes you very hungry and determine.... I would have put up with much more humiliation and insults that to steadfastly purse my dream." That toughness runs through Maria even today.
