Thanks for the great "shift" tips Alan.   I wonder how much of being positive is, in fact, genetic and how much can be learned?  I, too, had a Mom who loved to sing and was often called "Polyanna" for her look on the bright side mentality. She had setbacks but always maintained that "things will be better" and said it was because she was born in 1932, when things were REALLY bad. Because you shared your Mom's song,  I thought I would share one of my favorite songs she would sing when we were driving home in the car:
Here we are again. Happy as can be.
All good friends and jolly good company.
Never mind the weather, never mind the rain.
As long as we're together...whoops! She goes again and again.

Keep on keeping on with the posts.
