Megalomania is a mental condition affecting numerous high-powered superior human beings who were obviously destined for greatness and whom you could never hope to match. Well, yes anyway, as I was saying before I got sidetracked, megalomania is defined as a preoccupation with obsessive fantasies of limitless wealth, power, brilliance or beauty or even all four. Megalomaniacs are usually either obsessed with gaining these things or may believe they already possess them. In most cases, they already possess all four.
