Another inspirational 30-day challenge for Ambassadors earning their Photographer badge. (Spending a month taking photos of things they're grateful for could also spark some ideas for a Take Action project related to the Bliss program...)
It's not so much a "challenge" as it is something to inspire you to be present. Don't let the word "challenge" scare you and prevent you from participating. There's no reward, no punishment -- just an opportunity to be more present.
