All milestones met, achievements made, and unexpected successes and adventures you have throughout the year, you write down on a piece of paper and pop in a jar.
You can decorate this jar to fit in with your decor and keep it somewhere visible to remind you of the practice. A simple thing to do is diarise a date at the end of the month. Then take a moment to think back on the month to what to include in the jar.
For fun write on coloured paper or you can decorate your memory.
At the end of the year as a celebration and reminder of what has happened, you open the jar and read through all the pieces of paper. Then you can see all the things you are grateful for.
Extra fun is decorating a jar for a loved one or someone that you can share the content of your jar, as they are willing to also share with you.
