what's the difference between achievement and ego?

It's not 100% rule, but it is a cue USUALLY:
People with achievments usually don't praise their own work, other people praise their work. People with ego usually constantly praise their own work and tell others how great they are. Someone who's actually great doesn't need to say how great they are, everybody around them already knows it.

We have a saying in my language(I think English has something similar too): "The baker does not testify his own dough" - Meaning that speaking highly of your own achievements/creations, means nothing, others should speak highly of you or your actions to give it meaning.

@-red dotii is jestdotty, matrix as in the communication protocol, we have a matrix room.

Achievement: Actions
Ego: a mental image of yourself

Talking about achievements: talking about your actions

Talking about ego: talking about your identity

@jestdotty "How can anyone control the news"
By owning them? In many countries pretty much all news stations and papers are owned by a small amount of politicians.
