The easiest thing in the world is to criticise and the hardest thing in the world is to understand and forgive. that's why many people live in loneliness even though they are constantly surrounded by people.
In the wise words of Dale Carnegie (American Author)
"When dealing with people, let us remember we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity."
Never make an impulsive judgment about a person because we are often shown only the one side of the story. A sign of greatness lies in understanding the circumstances rather than the action. A sign of greatness lies in forgiveness and not in anger or impulsive decisions. A sign of greatness lies in getting aware of your ego. Always make sure that you have all your facts straight before casting a stone In someone's path.
As they say "Any fool can criticize, condemn and complain – and most fools do. But it takes character and self-control to be understanding and forgiving." Forgiveness is the attribute of greatness because weak people find it impossible to forgive.
Before Criticising someone, always be aware of your ego, your mistakes and your failures. that way you will always be more understanding, more empathetic and kinder.
in the end, As Plato Once said "Be kind, for everyone you meet is fighting a harder battle."
