Gratitude Letter
Close your eyes.
Think of someone did something or said something that changed your life.
Write a letter or SMS or WeChat of gratitude to this individual

Be specific about what he did for you  or said to you
How it affected your life.
Let him know what you are doing now

Mention how you often remember what she did and said
When you meet him, take your time reading your message again

We benefit from the pleasant memory of the past
We lead by example
We strengthen our relationship with them

No one has addressed the eternal question of what begets happiness with more rigor and empirical dedication than Dr. Martin Seligman, founding father of Positive Psychology — a movement premised on countering the traditional “disease model” of psychology, which focuses on how to relieve suffering rather than how to amplify well-being. Seligman, whom I first had the pleasure of encountering at my alma mater, the University of Pennsylvania, and who was once elected President of the American Psychological Association by the largest vote in the organization’s history, remains one of the most influential psychologists in the study of happiness. This exercise is taken from his bookFlourish: A Visionary New Understanding of Happiness and Well-being.
