Each morning during fifteen- minute bath, I determined to cultivate a big, happy smile. I found out it had to be an honest-to-goodness smile from down deep , an outward expression of happiness from within! Let’s see how the smile muscles me during the day. I would think of the things I had to be for, work up a big smile and then enter. It people when I passed them on the street to give them a smile. Give every living soul you meet the best smile you have smiled in your life, and see how much better you feel and look. It’s one of the best ways to worrying, and start living. When I began to do this, I found I became more welcome everywhere.
