"If virtue is not worthy, it will be tiring" means that a person's moral character, contribution and life he enjoys must match his position. If the contribution doesn't match the life you enjoy, it means that morality doesn't match, so it will harm others and yourself, which will lead to disaster. If you really understand the meaning of the sentence "virtue is not worth it, it will be tiring", life will be very different!
The phrase "if virtue is not superior, it will suffer" not only refers to those who are in high positions, but actually everyone has the problem of whether virtue and position match. So is a family. If you are a match, your life will be relaxed and happy. If the moral position does not match, then you will always be in trouble and pain, and suffer for it.
