I love this post and would really want encourage the writer. Ego is something that is naturally in every man, but the ability to suppress it is gold. Everyone has got it, sometimes one can not help it, jbut all the same to live a happy and not tangle oneself with toxicity, one has to actually let it go and embrace happiness.
Although people take letting go of your ego for peace as weakness and stupidity. I think in this case one should strive to be enough for self just like you rightly mentioned in the post.
