You're never too old for a star chart. There is just something gratifying about filling in your accomplishments in the shape of a star and stepping back to see how much you've done. These templates are for opening or closing duties and gives you space to list your duties with stars for each day of the week. At the end you can add a way you are going to celebrate your effort (I suggest the celebration be for your effort, not for being perfect at the star chart).
