The Box of Gratitude has everything you need:
Six beautiful notecards, an instructional guide to writing notes of gratitude, a worksheet to keep track of your journey, and a donation to the National Coalition for the Homeless with each purchase.
How it works:
Think of people in your life that you are grateful for. Write them a simple note telling them that you are grateful for them, along with the reason why. Be specific. Watch the magic unfold as you thank those around you for being a part of your life.
