Don't make hasty judgments about others.
Trying to understand the possible reasons for others behavior will keep you from making unfair or hasty judgments about others. Others are struggling along in life just as you are. Sometimes unattractive traits cover up a reality that is the exact opposite.
The clown may be unhappy; the bragger insecure; the person who laughs to much may be nervous; the aggressive person may not feel secure; the person who seems to be avoiding you may be shy. In addition, there are often stresses or problems in peoples lives that affect their moods and their ability to cope at work .
Give others a chance before passing judgment!!
