[Objective]

I have read nothing but I believe it's impossible to not be egotistical as human motivation and survival bases itself on it. Even helping someone else is egotistical because it makes you feel great. Even if you go out of your way to do so you wouldn't have helped them if it didn't make you feel good in one way or the other.

By being humble and polite is to put yourself in a good light (or because it makes you feel good due to the way you treat others, a pretty common personal trait at that too) is one of the most egotistical things you can do. By not being humble and polite you are egotistical as well, but at least you are true to who you are at least which in itself is also stroking your ego. We're all egotistical douchebags, and some of you may even think "well, fuck, I'm not as egotistical as that person at least", whoa, stroking your ego on top of it? Bites teeth and breath air fast inwards for a sec while making a slightly awkward face in the most ego way possible.
