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
 

I think this quote is very true. I think it’s pretty similar to the concept that if you always complain than you will never be content with anything. Some of the happiest people don’t have that much because they don’t complain about it and are thankful. Being a snob and always wanting more is not the reality in life. If you are thankful for everything that you have than if you ever gain something than you will be so much more thankful than the people who always get things.
