Gratitude journals are a popular and effective positive psychology intervention. The goal of a gratitude journal is to increase the focus on positive experiences, which improves well-being.
Keeping a journal of the things you are grateful for, has been shown to have a powerful effect on mental well being. Journaling also helps reduce stress, increase happiness and improve self-esteem.  In order to keep a gratitude journal two times a week write a detailed entry about one thing you are grateful for. Take your time and don’t rush through the process. Remember you can write an entry more than twice a week.
