Yes there are those great geniuses and wealthy men who act in a way perhaps that we envy, but most ego problems come from our own inability to recognize exactly (or even closely) who we really are. We are by most, fragile and imperfect individuals with many faults. Whereas there certainly is nothing to brag about our lackings, certainly knowing our faults is much preferable to thinking that we have none.
If we would merely admit to ourselves that we lack in many areas, we would see that we would become more of a comfortable person to be with. Most inflated egos are byproducts of depressed egos; a need to be recognized, a need to be the best. When we come to grips with the fact that others have much more capabilities than we do, we can begin to become more socially inclined and get along much better with all people.
Remember, it is only the person who knows little that thinks he knows it all. The more a person knows, the more he realizes that he doesn't know much.
