American minister and writer Norman Vincent Peale wrote this in one of his books called The Power of Positive Thinking: “The way to happiness: keep your heart free from hate, your mind from worry. Live simply, expect little, give much. Fill your life with love. Scatter sunshine. Forget self, think of others. Do as you would be done by. Try this for a week and you will be surprised.” From “The Fuel that Destroys Depression “ by Dr Rob Carmen.
