Look on the bright side of things, There is always a rainbow after a storm, Look for the silver lining, Chin up, Smile, Cheer up, Think happy thoughts- the list can go on. Be positive- it sure beats the alternative!
One writer documents a full year- 2008- of her daily gratitudes on her blog. She wants to discover for herself if "The Law of Attraction" has any merit. The Law claims that by following some rules ( "like attracts like" for example) - your life will overflow with abundance and happiness.
As the book "The Secret" promises: "By thinking pleasant positive thoughts (like gratitudes) one can access the untapped power within and this revelation can bring joy to every aspect of life."
