Honor vs Self-Improvement
An honor-seeker is not really interested in self-improvement. He is only interested in gaining approval from others. Hence, he will disregard his faults as long as others will not notice it.
On the other hand, a person who is able to forego honor is able to focus on truth. His only thought is to do the right thing, and he is willing to sacrifice his honor for his principles. Such a person will eventually receive honor, for he will constantly work on improving himself.
