Giving priority to one's own interests.

His egoism shows as he pulls the shared platter toward himself.

At a shared meal, one adult greedily pulls the entire serving platter toward himself while companions are left with empty plates, focused only on his own interests.
Etymology

The “I” at the center of egoism first supported a theory about knowing only one's own mind. The word later covered pursuing one's own interests and then self-centeredness.
