As the old joke goes, “I know I have been talking a lot about myself and all my accomplishments, there were quite a few, of course. But I really should stop talking about myself. So, what do you think about me?”
I imagine we all have been in the position of the listener above. Somebody goes on to talk about themselves and we might wonder, “When will this end?” There can be any number of reasons why somebody places themselves in the center, it doesn’t necessarily mean that person is a narcissist.
It’s quite possible, for example, that the person is excited and wants to share something important that happened. Or perhaps the person grew up in an environment where accomplishments were denied or minimized, so the ability to talk about self is an important self-growth step and intention.
