Ego, What is Ego? Options

As a person, I have a big ego. I want to win at all costs. I want this and that. I simply want to have it my way. I want the cake and the icing too. I am spoiled and always want to take more than I give back. Is this an example of an Ego?

My ego boost me to gain riches, health, love and many other conquests.
My ego also make new enemies, destroy and corrupt various aspects of me and my environment consciously and subconsciously.

What is EGO? What does this word means?
How do you define it? How do you keep it your slave instead of it enslaving you?

Let's try to clarify and define what "ego" first...
Ego = Values?
We live our life with sets of "conditioned" values mostly from our childhood and environment. When someone born and being feed with silver spoon, they usually has a set of values they follow, ie. they will dine in higher class restaurant, date only a person from certain social class, or certain standards, think and behave differently, etc. Ego?

Like I posted. I don't negate the word "ego" so this is my "conceptual" take on it.

Balanced Ego = Wisdom?
If so, then what is Wisdom?
Knowledge being put to "good" real life practice converted to experience which later become wisdom?

But then, what is a "balanced" wisdom?
Hmm.... I'm talking to myself... just ignore me (IMG:style_emoticons/default/hmm.gif)
