My jar of "wish rocks" that I pick up from the beach each time I go. A wish rock is a rock with a stripe that goes completely around it. You pick it up and make a wish. I'm not saying that the wishes will automatically come true. (Some of my wishes absolutely did not) But for a brief moment, you feel hopeful that it will.
And if you have an entire jar of them in your house, you can feel hopeful whenever you want!
What do you wish on and what makes you hopeful?
