Have you seen those that throw around their weight and status, just because they can? In other words, they are a big bully. Have you seen those that abuse their power just because they can? It makes you wonder did they ever consider that it was unnecessary and that possibly they could have been nice and considerate to others. Granted there may be some people that you cannot be nice to. There may be some people that may attempt to run over you when you are nice to them, but think about when you weigh whether it is more nice to be important or important to be nice.
Have you considered it might be more important to pay attention to details? When you meet someone are you attentive to what their name is, what their likes are, what it is that they do? Do you mention their names several time during the conversation? Or is the conversation all about you and what you have, what you are doing in life? Is the communication just one sided?
How many have alienated family members because they felt they were better than them? Do you know of those that feel because they have more material things, they feel their other family members are less than? Do you know of those whose parents have struggled to raise them, send them to college only to find that the "spoiled brat" does not appreciate it .
Have you notice that some wealthy people will talk with humor? Have you ever noticed when some people are giving talks before an audience they may open with a joke to get the audience laughing and loosened up? Even though they may be important, they know it is important to be nice and sometimes funny as well.
Have you ever been around someone that would throw big names around in an attempt to impress you? They probably only know of the person, but want you to think they are great friends with the person. I would say this is somewhat deceitful. Again, it is nice to be important, but more important to be nice.
