I absolutely loved this article.  I am an instructor and trainer and often times have to evaluate others.  As the leader of the team I am often the one who has to address hygiene, performance and behaviour issues and criticising others is not easy as you have to be conscious of their feelings and how they may receive what is constructive.  However,  I have learned over the years to be considerate of other's feelings and put myself in their shoes.  I have also learned to take criticism positively as it too helps me to grow and improve myself which in turn means I can critique without being harsh or unkind.   The greatest satisfaction is seeing how a person changes themselves or work on the areas that need improvement.  I welcome this and more articles like these.  Thank you
