Before you condemn others, take a close look at yourself.
It is very easy to condemn others and make them feel terrible, it is very easy to look at people with disgust and make them feel very miserable, but in most occasions, we fail to carefully observe ourselves before we condemn others.
Life can be filled with issues and conditions of life, life can be filled with reasons for us to act in an unpleasant manner and when we do, we often forget that others have flaws as well.
So before you really condemn your actions, ask yourself truly if you are perfect.
