I have been amongst the best players in the world for 8 years. None at that level played as many ties as I did.

Whether it's in the right way or sometimes the wrong way, you learn about life and its lessons.

The more kilos you have to move around, the more it weighs on your knees. Then of course in terms of stamina, the way you move around, it's a little extra. It might not be much, but when you exercise with two, three extra kilos, you can feel a difference; it's important.

Yes, I have had difficult times on court and at certain tournaments but you need to forget about it and go forward because that's the way it works in our world.

It took me time to adjust and to realise it was not going to happen like it did in the juniors.

If you are not physically strong, it's difficult. But at the same time, I think you need something more than that; you need to vary your shots, as Justine has been able to do in Amelia or Charleston, where she beat her -- I can't remember where it was on clay. So you need this kind of thing. But of course if you're not fit, you'll never make it through.

You have to adjust to where you are but the French are all together - the guys and the women. It's good.
