im looking for some profound psychology writings that analyze the human condition and mind and all of that, as i am trying to figure out what will make me more happy/content in life....
im looking for work that focuses on our lust for power and the way we manipluate the world around us and judge everything from our human perspective.

While I'm not sure there is a work that can fit both of these critieria, I'd recommend Das Ich und Das Es (literally translating to "The I and the It" but you'll find it under The Ego and the Id on Amazon most likely)

Freud seemed to have a pretty good handle on our lust for power and manipulation and things of that nature. That book is a classic. I wouldn't call it an easy read but it has a lot of great ideas.
