There is such a thing as a healthy ego. Life would be bereft without it. But often we simply - from our earliest years, do things, act out, simply because we feel the need for more and more attention.
We want to be validated by others and that's not all bad, but it can be less than helpful in finding and developing our true identity, our vocation and place in life.
A fulfilling life means that we find our gift - and give it away.
