I think Serena has always been humble and spiritual, but I think since her sister's death she has put life in a different perspective.
Spiritual, maybe... but humble... please!! Serena Williams has never been humble and probably never will. She's the least humble player on the tour.
And though i do admire her as a player (I mean she has a great game), my problem is that i've always HATED arrogant people or people not capable of humility. We've all known people like that around us, and to me, the fact that they are actually good doesnt change anything. Some people are great and dont feel the need to brag about it. Look at Graf for example.
To me, a lack of humility denotes a certain lack of intelligence. Because this is just plain rudeness, and direspectful.
But from my personal experience with these people, I think they feel the need to constantly brag because they actually have a problem of confidence... at a certain level, they always feel they have something to prove to others, and to themselves.
But again, to me, its not excuse.
And please, Serena fans, before u call me a hater or something, I'm just expressing an opinion.
