21 Days of Gratitude Challenge. It can be big or small moments of gratitude. You can use the free printable prompts provided as a journal, photo or status update to help you focus on the beauty that surrounds us.
30 day gratitude photo challenge: Gratitude Positively Present is an AWESOME site if you're not familiar with it yet. But I sometimes feel like photo challenges can cause us to get too become too perfectionistic, which makes gratitude super hard!
