An honor-seeker will not be a truth-seeker. To gain others’ approval, a person will have to keep changing his opinions to agree with the person with whom he is talking.
In the end, he will lack the respect of others. Those who manipulate him will recognize that he agrees with them only to gain their approval and will hold him in disdain.
Only if a person talks and acts according to his ideals, independently of what others think of him, will he gain the respect of others.
