Yeap. I know your point. But I wanted to tell everybody is building his own imaginary world (model of reality). Maybe you are good with yourself in yours world, but somebody else don't.
For example: First case. Somebody is born in a concentration camp, and he takes this condition for normal. He is happy, beacuse feeding time is coming.
And second case is some rich bitch with big nose, and her world can be a living hell ;)
So all is mental/perception. Our difference lay in models of reality we building.
Hard to be real, when u don't know what reality is, and all u know is learned/culturally conditioned not necessarily real.
