All the time! By bringing gratitude to the forefront of your mind you make it a habit. So start thinking right now about all the things you have to be grateful for:
Nourishment of All Kinds
The Clothes You Wear
And that doesn't include all the specific blessings you receive every single day! There's so much to be grateful for . . . all you have to do is allow yourself to see it. And then express it - here and in your heart. All the time.
