This step involves writing a letter to someone who deserves gratitude and doesn’t receive it enough. In principle, this can be anyone from the social network (friends, partners, family, classmates, etc.), that but preferably someone you can meet with, be it in person or online.
Research in the field of positive psychology shows that the Gratitude Letter can be a great gift, improving both your and your recipient’s mental health and well-being.
