“Criticism, like rain, should be gentle enough to nourish a man's growth without destroying his roots.” Frank A Clark
A magical route to getting on with people is to accept criticism from them. No, go a step further and INVITE criticism from others. Better for you, is the man who tells you that you are a fool, than the one that keeps quite and thinks it. A person that tells you that you’re perfect can’t help you to grow and develop, but the person that offers criticism can.
