Keep A Gratitude Journal
Dr. Robert Emmons studies gratitude at UC Davis, and recommends that people keep a gratitude journal to increase happiness. Since gratitude is a positive emotion, dedicating time to think about everything you’re grateful for with automatically boost your mood.
You don’t have to commit to it daily, either. Professor Emmons told The Huffington Post, “Doing so 4 times a week, for as little as 3 weeks, is often enough to create a meaningful difference in one’s level of happiness. Another exercise is to write a “Gratitude Letter” to a person who has exerted a positive influence on one’s life but whom we have not properly thanked in the past, and then to meet that person and read the letter to them face to face.”
