ego versus selfimportance

I don’t know if ego can be related to a sense of selfimportance, since selfimportance can have a component of humbleness in my opinion, since you know that ackording to nde’ers, everybody is precious and important and loved by the almighty and the angels and the holies, and everybody has a special mission, so a component of humbleness might accompany such a feeling in my experience, but ego maybe something different, maybe putting oneself always in the first place.
