I'm going to write about something that comes to my mind very often. It's about a human characteristic, or a part of every single human: the ego. I know it sounds tedious but I think that thinking on it is good for everyone, because ego is the "thing" that makes a person to hate another person, or just something of it.
Bringing out ego  means that you put yourself on first priority on everything; on a conversation, on a decision, on arguing, or in any collective activity. Ego also appears on single activities; it is always there, so you cannot evade it and that is maybe the problematic thing: people seems to forget that they are not the only ego in the word. Because, as I said, everyone has an ego, which is very strong.
Is just a natural fact:  a person always have itself on his own presence (he can't go and leave itself on his home; he is he, and goes with him to everyplace), and for other side a person have the mision to survive in the world, so it's normal that his mind is always focusing on itself also.
So ego is a complicated topic because it is completely natural, but it affects really hard on people's relations. What I propose is something very simple. Because a person ego is always there and it's not going to go to any place, it is better for him to become aware about it and save certaind attitudes for different context. It is not necessary to show your ego, because people can see you and apreciate you perfectly. So, different as you, other people will perfectly apreciate and value the talents or ideas that you have just with your presence and humbleness. Humility is always the best valuated thing on a person.
So showing ego is just a personal whim that tries to satisfy or corrobarate on the others someting about yourself. But it's not necesary to do that! It is best to save your ego for joking or for recognising your own efforts when you are on a nbad moment. Ego is an unavoidable fact that can be dangerous for your relations if you are not conscious of it, so it is best to channel that impulses on different contexts to benefit from it. It have a social utility.
