A few quotes on thankfulness, with a nod to Faith, who first linked to a page on gratitude at which I found these quotes:
The unthankful heart... discovers no mercies; but let the thankful heart sweep through the day and, as the magnet finds the iron, so it will find, in every hour, some heavenly blessings!
~~ Henry Ward Beecher
Only a stomach that rarely feels hungry scorns common things.
We can only be said to be alive in those moments when our hearts are conscious of our treasures.
~~ Thornton Wilder
