Looking for a quick take away tool without need for a device or a pen?
Here is a nice one that you can do anywhere anytime.
It will just look like your counting with your fingers!
“To come to a positive appreciation for the small things in your life, you can try the gratitude exercise. It simply means that once a day you bring to mind ten things that you are grateful for, counting them on your fingers. It is important to get to ten things, even when it becomes increasingly harder after three or four! This is exactly what the exercise is for—intentionally bringing into awareness the tiny, previously unnoticed elements of the day.” (Williams and Penman)
Give it a bash and if you feel so inclined afterwards get to it!
