We should not take pleasure or delight in finding fault with everything and everybody. Do you want to be thought of not seeing good in others and only delight in your findings? We should not rejoice in saying , "I told you so." that is a wretched way to live, to have the only positive thing in life to find something wrong with nearly everybody. We do not need to amplify the gloomy side of man's existence - the human side of this traversal - while giving little emphasis to a life of service by one who is bound to make a mistake while trying to do his best.
Try building up someone and you will be surprised how good it will make you feel!
