a friend of mine from Northern Italy send me the link below. i am not sure if he was reminding me of what a great standard of living he has or challenging me to remember the importance of being happy. in any case, he suggested i read pages 8 and 9. i ended up reading quite a bit more. it is worth a perusal.
