What you see is what you get?

So, another really interesting midnight conversation with a friend (when we were supposed to be studying really hard, mind you), was utterly shocking for me. He made me realize something so very true- it all boils down to looks. I mean, yes, I've always been cynical in terms of the shallowness of humanity; I myself have displayed various streaks of shallowness in the past. However, when put into perspective, so many acts are based on looks- on how attractive the other person is, how attractive we think we are. People who are attractive get away with a lot, have the more outgoing and confident personalities, and genuinely do draw more attention.
We took into account the people around us. The extroverts are, in most cases, the people who are confident about their looks. Even people who aren't inherently extroverted gain the most attention, care, and company, if they are good looking. Very rarely do you find an exception to this case, unless the persons' personality greatly outweighs their looks.
This conclusion, and, well, realization after taking a look around, was a genuine eye-opener for me. For someone who claims to thinks so much, I have surprisingly never thought of things from this perspective; probably because, up until now, my views on shallowness have been slightly selfish.
