I like the author's use of the word "modesty", but maybe "humility" is really what we're looking for. Modesty means balanced and moderate, but sometimes leaders need to take feedback without trying to balance it (i.e. defend themselves). Take their lickings, so to speak. Those are the times that true growth happens.
That's an interesting point. I hadn't really parsed the difference between the two terms, but there is one. I think it ends up calling for both, depending on the situation.
