How would you describe or depict about Serena's win or her desire?

I would say Serena is very tenacious, determined and resilient . We have all seen her incredible comebacks, saving three match points against Sharapova at the 05 Australian Open and her 07 victory ranked 81. Then Wimbledon fighting through a pretty bad cramp. When she really wants something she is going to go after it 150 percent. I think Richard is right on with his descripition, although the comparison to Mike Tyson is a little scary lol.
