I’m interpreting this as hyperbole, similar to ‘killing these push-ups’ or something like that.
I hope you don’t actually want to destroy your ego. Maybe just to diminish excessive, hubristic egocentrism?
Out-of-control egoism is definitely horrible. But the ego itself is a miracle. Just needs to be properly tempered and healthily balanced.
I’m fairly confident that you’re already aware of this, @Sub.Zero. I’m just typing it out in case anyone on here might read ‘kill the ego’ and take the meaning a bit too far. (I was definitely the kind of teenager who tended to take things like that too far.)
So just to be clear: We need our egos to have healthy psychological lives. We also need to transcend our egos to have healthy lives. “Both…and…” not “either…or…”.
