Why have you only chosen black women? I mean, I suppose there is a lot of comparison between white blondes on this board, so I'm not suggesting any sinister intent or undertone here...but still, there are only 4 black women and you've picked all four. Two black people can be as different as two white people.
Venus and Chanda are totally different people. Chanda is a professional and a genuine, nice person - or that's how she comes across.
Venus comes across as self-absorbed (a Williams trait), aloof, narcissistic (another Williams trait) but at the same time she has a philosophical side that Serena doesn't have, and a lot more restraint. She also has a tendency to brag, which, dare I say it, is an American trait. To British people who like to be self-deprecating, I'm afraid it's vulgar. Although I suspect in Venus' case some of it comes from her roots, where the "don't let them tell us we're not good enough" mantra has been passed down the generations.
To be fair, like her sister Venus seems like she prefers to focus on the positives and dismiss the negatives, both in her general outlook and in the way she sees other people, which I like. She prefers to say positive things about people and I do detect that if you know her, she's a very kind and loving person.
Serena's ego is even bigger than her butt, to put it bluntly. She has the same philosophy as Venus, probably inculcated by her father, that she can do anything if she puts her mind to it. And who can criticise that? Me? I don't think so. God I wish I was like that some times.
But Serena, in my opinion, as a result of all these distractions has no concept of where her real talent lies, and because of that she will quite possibly never get the best out of her tennis career. Like her sister, although to an even greater extreme, she's very seduced by the allure of celebrity and being photographed, almost in order to raise her value as a person. I don't see a philosphical side to Serena, only one of "I can do anything, I'm the best, I'm beyond criticism".
On a more positive note, like her elder sister I can see that she prefers to say positive things about people, she's highly intelligent (even if I feel she misuses her brains) and probably a very kind, warm, upbeat person to be around when you're not feeling too good.
Alex Stevenson, meanwhile, is a complete nutter. Totally self-absorbed, raised to believe she's a diva, and basically a spoilt brat who's never been told a few home truths. I remember watching one of her practice sessions. She spent the whole time being fed balls into the middle of the court which were basically put-aways. She wacked the living daylights out of the balls and then proceeded to serve a series of balls well in excess of 100mph. There were no rallies, or fitness training or tactical advice, and no interaction with the other players. I thought that was symbolic of what seems to have been her upbringing: she's fed the shots she likes to hit in order to boost her ego, so that she can believe she has more power and talent than she's ever proved to be a reality.
