"Think of what you have rather than of what you lack. Of the things you have, select the best and then reflect how eagerly you would have sought them if you did not have them."
- Marcus Aurelius
This is a great thought to keep in mind. Sometimes it can be hard to focus on the good rather than the things that are troubling you. Things that crowd your thinking and can seem like a thunder cloud over your thoughts.
There's always a way to find something positive even in the worst things in your life. It's a way of thinking. Of living. Again, not always easy to do, but brings infinitely more joy or satisfaction to your every day.
