If you wish to lift a man, it will take praise and not criticism.
We believe that pointing out the flaws and shortcomings of a person will encourage her to do better. It serves quite the opposite purpose. It further discourages and saddens the heart.
The reason is that we already know our flaws and shortcomings. Having them pointed out only teaches us that others are not noticing our contributions, but our mistakes.
Praising the goodness of a man breathes life into the spirit by making him aware that others are seeing his efforts.
It is a sure fire way to make certain he will repeat and go even further.
