Gratitude is the Attitude
Your attitude should be filled with gratitude.
"The Pilgrims made seven times more graves than huts. No Americans have been more impoverished than these who, nevertheless, set aside a day of thanksgiving." ~H.U. Westermayer
The first thanksgiving was filled with gratitude because the pilgrims were very grateful that the Indians didn't want to kill them anymore and they got to eat lots of food.
