Thankfulness is realising and appreciating what you have.
Be thankful, because you have more than others! If you see no reason for giving thanks, the fault lies in yourself. (Indian proverb) I had no shoes and complained, until I met a man who had no feet. (Indian proverb)
Be thankful, because you have been given much! If you can read this, thank a teacher. (Anonymous) When eating fruit, think of the person who planted the tree. (Asian proverb)
Be thankful, because it will shape your whole life! Be thankful for what you have; you'll end up having more. If you concentrate on what you don't have, you will never, ever have enough. (Oprah Winfrey)
