Gratitude is the king of all virtues. Without it...there is no happiness in your life. It's really that simple.
Here's what Melody Beattie said:
"Gratitude unlocks the fullness of life. It turns what we have into enough, and more. It turns denial into acceptance, chaos to order, confusion to clarity. I can turn a meal into a feast, a house into a home, a stranger into a friend. Gratitude makes sense of our past, brings peace for today, and creates a vision for tomorrow."
