Criticism is defined as a critical observation or remark.

While criticism can often be an indispensable source in helping us grow, it can never take the place of having the courage to stand in the arena. Many are quick to tell us where we have gone wrong but stand on the sidelines, afraid to get their hands dirty. It is the doer of deeds who counts in the battle for life, not the man who looks on and says how the fight ought to be fought, without himself be willing to share in the stress and the danger.”
