All of the Russina's. Justine Henin has just as much mental toughness as she does great physical conditioning. And some of that mental toughness comes from working out so hard and sacrificing so much. Juju even works out when she's not feeling well. Justine is the most talented tennis player on the WTA Tour. But she also has the best work ethic on the WTA Tour. Combine the talent and the drive to succeed and you have Henin's formula for success.
Happiness is like a cat. If you try to coax it or call it, it will avoid you. It will never come. But if you pay no attention to it and go about your business, you'll find it rubbing up against your legs and jumping into your lap. - William Bennett
No, Knizzle, they just meant that Justine could show Venus how to have mental strength!
Pat Etcheberry didn't teach Justine that, or Venus wouldn't have embarrassed Juju 6-3, 6-3 at the Aussie would she?? You know what you are saying is way off, I don't have to tell you. All she can teach Venus is how to be a cheater and Venus doesn't cheat.
