Great article! It identifies what I think of as the illusive fine line. I wonder how many of us have just said "thank you" and tried to be self-effacing by including others that have helped in small ways with a success that we are primarily responsible for, then kicked ourselves for not owning it more when others are credited with the work. Sure, it's ego, but it also affects perception and promotional opportunities. In the workplace, not everyone "plays fair" and that sweet spot can be difficult to find, but your article has made me resolve to try.
