You have to compare ..

If this morning you woke up healthy - you are happier than 1 million people who will not survive this week.
 
If you have never experienced war, imprisonment, torture or starvation - you are happier than 500 million people in this world.

If your refrigerator has food, you're dressed and shod, you have a roof over your head and a bed - you are richer than 75% of people in this world.

If you can go to church without fear of harassment, arrest, or death - you are happier than 3 billion people in this world.

If you have a bank account, money in your wallet and some change in the bank - you belong to 8% of wealthy people in this world.

If you are reading this - you do not belong to the 2 billion people who can not read.
