What if the thing you wanted most were given to you - would you know what to do with it? Think about what that would mean. What would you want? A new job? A new relationship? A new house? All these things are material and thus prone to change and disappointment. If you have your health you have something that is immaterial and thus more precious. Use the favorable aspect of the day to focus on what you really want. (Hint: focus on your health!)
