Excellent article. Have been keeping a Gratitude Journal for 9 years, pen to paper, made up of my 3 favorite 'moments' of each day.
What works best for me: writing them as emotionally-charged as possible, in less than one line each. No broad-brush statements, no "my house, my family and my job" repetition which lose steam and impact over time.
In 2020, which so many people referred to (saw it many times on social media) as a 'total crap storm'...managed to record about 1000 'moments'.
In my work with Visualization and Vision Board clients, I encourage them to express Gratitude, daily, for the progress they are making toward their goals.
Please keep on sharing your great articles and interviews!
