Gratitude seems to be the rent we pay for walking this earth. I find that the more we pay - the more thankful we are - the bigger this space gets.
So our life isn't some space-restricted venture, listed and limited in scope and size. We start to understand just how big and wonderful this life really is when we are as thankful as possible.
Once you start listing your blessings you'll see just how many you have. And the list will always be longer than you could possible imagine.
