On a linguistic note
Greed is often associated with wanting more than your fair share of something...money, power, the cookies on the plate...
Examples of Greed
My need/desire for booze was a little more basic than that. I didn't really care how much anyone else drank I just needed it myself.
I became very selfish with it. Greed just isn't a word I personally would use because it doesn't seem to fit.
