Maria Sharapova discussed the origins of her famed mental strength
"I'm not really sure. That's a question I have been asked before, but I think it's also life circumstances that you go through, that you work through, and learn from. Also by the people that you're surrounded by and what you learn, how you go through making decisions. You know, I have never really had an easy journey to this step of where I am today. From my days in Russia to even now we always go through challenges and adversity. I think we're still not sitting here today saying I'm the strongest person or physically or mentally, because I always want to improve and be better and make myself a better person.
