I love this quote. It comes from Oprah Winfrey: "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."

And that’s so true. We’re often complaining about what we don’t have. Well we’ll never have everything, right? Do you really want to complain your entire life? Instead focus on what you do have and all that’s good in your life. It’s the best way to live.
