Egoist or egocentric?

"Egoist or egocentric?" What thoughts are spinning in my head .. no, am I really turned around? I look at the Rose cut diamonds and the modern Kr 57 cut diamonds and wonder why in the old days the cut was more for those around you, but now you need to "look" into the diamond to see all the beauty? The brilliance of the surface faces of a rose cut diamond penetrates many meters of space. The game of modern cut diamonds is intended rather only for the owner.

The egoist says: "I am the center of the Universe. Therefore, all of you around me should perceive me this way: you should jump around me, please me, do everything for me, sacrificing your interests for my interests."
The egocentric says: "I am the center of the Universe. My personal Universe. It is so great, so interesting and so beautiful that I do not need anyone else. Therefore, you are all around me, with your problems and concerns, with your interests and desires, with your opinions about the world and about me, mean absolutely nothing to me. "
These concepts are both close and diametrically opposite, as are the brilliance of old and modern cut diamonds.
