Nadia Comaneci

Of course, most people remember that I received the first perfect 10 in Olympic gymnastics competition.

I don't run away from a challenge because I am afraid. Instead, I run toward it because the only way to escape fear is to trample it beneath your feet.

Enjoy the journey and try to get better every day. And don't lose the passion and the love for what you do.

My first career ambitions involved turning into a boy; I intended to be either a railway guard or a knight errant.

I know my Beijing medal has been a watershed moment in the history of Indian boxing, but personally speaking, I would like to better it in London.

I still have the desire to succeed, and I've always felt success is measured by what you've done in the win column, not top 10s.
