the con criteria

They embellish themselves using appropriate-self serving language meant to eventually altar existing thought processes and patterns to benefit themselves. They are conscious of every word they say and they use perceived weaknesses and vulnerabilities in people to fulfill their desires; and it is in this way some people are evil. Then there are those who see benefits in the short term to fulfill desires. These people see no problem with their behavior because this world is a tough place and you need to deal with it. The world is a tough place because of these short term cons and the people who use them. I see this every day in people because it is used by the common folks or those with a junior high mentality.
So which kind of con criteria do you use? How do you use people to benefit yourself in both the short and long term? Remember, you are a liar so be careful as you think, you may trip on yourself. lol
