Getting along

Summary

Everyone has his own personality, and we show different personality at different place or momet. After readign this lecture, I realized thatthere are 9 main types of personality. We may like to ask bossy person about what kind of decisions we should make. To make an observation on girls and boys, it's easy to see the competitive trait in boys and cooperative trait in girls. Boys tend to find out who is the best and girls like to solve problems together.In the party, a person who is enthusiastic may be the most interesting person since they tend to ask questions about others.Helpful people are welcome for who needs help and .Innovative people have new aspects to see problem. people who are romantic or thoughtful do good jobs which make people feel the love feeling. Having doubt with anything is why the skeptical person can't be easily cheated.

Reaction

First of all, I pretty enjoy reading this lecture because it's quite practical for me,and I'm interested in how to get along with different people since I am used being shy when I meet

stranger,therefore, I learned how to show appropriate attitude when I'm in different circumstances or make friend with strenger. For my opinion, no one is perfect ; it's no way to

get everyone's identification.However, this lecture gave me a easy rule to follow,

that's "treat others they way you want to be treated"
