Personality has a great influence on communication between people. Firstly,sharing common interests is essential for initiating communication.If two people have completely different interests, it will not be easy for them to start communication with each other.Secondly, expressing their ideas and feelings freely is needed to develop meaningful communication.Some people fear that talking about certain subjects with hurt their relationship with their friends.They choose to hide their ideas or talk about these subjects very simply.Thus, they don't really have a chance to know or understand each other. The lack of understand leads to unsuccessful communication.To avoid unsuccessful communication, we must be honest and willing to express ourselves.
