Mia Wasikowska

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

It's very stressful being the No. 1 player in the world. You're in the limelight a lot. You've got more things to do when you get to tournaments, more things to do off weeks. But I wouldn't change it in any way because this is exactly where I want to be. I want to try and stay here as long as I can while I can because nothing beats this feeling.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.
