You would be quite amazed at what you can accomplish when you can get the ego out of the way.  We are speaking now not just of the prideful aspects of you, but any qualities that are part and parcel of the human vs. the eternal aspects of you, the soul.  What could you accomplish if you had no fears, no doubts, no guilt, no envy?  Need we continue?  Rest assured, we know that ego will be present in all that you do, for one side of you is human as long as you breathe.  Know, however, that the more you become aware of how ego holds you back from thriving, the more deliberately will you choose sides.  Shift allegiance.  Choose the spirit in all things and keep ego in its place.
