You can discover a great deal about a person when you compliment his or her triumphs. If the response is one of sincere gratitude and humility, that recognizes (through praise) the efforts of others, too, then that suggests the person has a character that is not self-absorbed or defined by grandstanding. If a person seems to frequently point out or brag about what he or she has accomplished, and tends to carry on about all the drudgery it took to achieve it, then you are speaking with someone who is probably insecure and self-centered, and looking for praise from you to feel good about him or herself.
Journalist Horace White said: Abraham Lincoln did not ‘put you at your ease’ when you came into his presence. You felt at ease without being put there.
It’s effortless to find respect for those individuals who have not allowed accomplishments or status to go to their head. They have their feet planted on the ground with the rest of humanity. Their humility is attractive whereas self-conceit repels. It’s illogical the amount of people who see themselves superior than others for any reason. It’s not possible to respect or like someone who believes he or she is better than anyone else.
Even as early as the first century people with arrogance and conceit were earmarked as disreputable and obnoxious, as seen in this quote from Seneca: You can tell the character of every man when you see how he receives praise.
No one should attempt to diminish the life or contribution of another person. Every individual is important and necessary for humanity. And now you know how to determine the individuals who believe that. Just give them a compliment, and wait to hear their response.
