What’s all that fuss about ego?

What’s all that fuss about ego?
…..after all ego (Latin: I) is just a viewpoint, a reference term – which might irritate, when overly used - but so does “you know”
“Egoists, Egocentrics & Egomaniacs” stem probably from the need to project and label something beyond the I – at least it would explain why ego is supposed to be synonymous for self. But what is self? – certainly not I, otherwise psychologists, mystics & gurus couldn’t make so much ado about it.
To me the term self encompasses what I am – including my ignorance about it – which doesn’t bother me, since I am what I do & I do what I am – thus having no problem with my self, and no desire to be someone else, or to go to a monastery to get rid of my self – which in my opinion requires an ego much larger than I can afford.
