Idealism-Realism dilemma: which one first?

Like the chicken or egg dilemma, this one is equally or more frustrating. I think let us first come into agreement what does it means to be realistic or idealistic.

When we based our calculation on the external world, we also configure our understanding so that we don't go astray with the model of reality. In a lot of cases, this means that all of us are pragmatics and take opportunity that exist wherever they are. But what if situation gets tough and we end up not being able to rely on our first model?

I think let's first reason out on why would someone want to move away from realism and pursue an idea which can only be completed only with idealism.

Let's assume that you got every information you have about the model of reality, but then, do you think it's just enough for you to understand the working mechanism of it but not knowing how to utilize it in the first place?

So then we are left with one task: How do you usually make the best out of your reasonable conclusion? The answer is, learn to go beyond the surface of reality. When you realize just how much potential you can go with thriving for your vision, you are able to comprehend everything as something that doesn't go against you.

Idealism in a sense comes from realism, but it's never the opposite. Our goals and perspective can shifted accordingly to how we perceives our self.

But in today's world, Idealism and Realism is seen as something contradictory, or somehow we can choose one of them but not two of it. When we start to make this conclusion, we can see why it's hard for us to properly integrate with what we dreams and what exist right now.

I guess you can see it as Idealism is inside of Realism. But I never see it as Idealism and Realism being in separate circle that's overlapped. The reason being, is that Idealism don't exist in the context outside of Realism.

Let's say you want to be a doctor, but you were born in an unprivileged family. But how were you able to dream of becoming a doctor? does the concept of "Doctor" exist outside of the context which it was established? No.

So I believe I have cleared any misconception here and gives a defining solution to a modern problem. A simple answer required pondering upon everything.
