gratefulness

If you had to pick an attitude that distinguished happy people from unhappy people, what would it be? For me, gratefulness would be pretty high on the list. Grateful people are generally happy, its one of those attitudes of choice that can may a significant different in ones disposition. So I wonder what you are grateful for from the last year? Why not make a gratitude list list and check it twice and see how your disposition ends up being happier.
