There were many occasions in my career where I could have given up, where I asked myself whether I would ever make it.

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.

I think I have handled things pretty well last year and this. What I have to do now is try do it even better.

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

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.

The day I stop feeling the pressure and I'm just enjoying myself and taking it easy is when I'm 35, asking for a wild card and playing mixed doubles with Arnaud Clement.
