Why does one create an image about oneself?

After writing the previous blog, I was thinking about why we want to create our own identity by affiliating ourselves to a country or a culture. I feel this type of affiliation creates a prejudiced view about other culture which we are not affiliated to. Moreover, when we create an image of ourselves of what we want/have to be, without acknowledging what we are, we end up having conflicts with ourselves and with our surrounding.

I read this thought provoking quote of JK, which came as an answer for few questions I had in mind, after writing my previous blog.

Why does one create an image about oneself? One has an idea, a symbol of oneself, an image of oneself, what one should be, what one is, or what one should not be. Why does one create an image about oneself? Because one has never studied what one is, actually. We think we should be this or that: the ideal, the hero, the example. What awakens anger is that our ideal, the idea we have of ourselves, is attacked. And our idea about ourselves is our escape from the fact of what we are. But when you are observing the actual fact of what you are, no one can hurt you. Then, if one is a liar and is told that one is a liar, it does not mean that one is hurt: it is a fact. But when you are pretending you are not a liar and are told that you are, then you get angry, violent. So we are always living in an ideational world, a world of myth, and never in the world of actuality. To observe what is, to see it, actually be familiar with it, there must be no judgment, no evaluation, no opinion, no fear.
