The celebration started in 1965 in Hawaii when an international gathering decided that it would be a good idea to have one day per year to formally express gratitude and appreciation for the many wonderful things to be found in the world. This day aims to remind us of the importance of expressing gestures of thanks and appreciation.
People are less likely to express gratitude at work than anywhere else. Women are more grateful than men. Gratitude could help you achieve your goals.
