This is motivational and funny. It's a good reminder to always keep looking on the bright side of things. When we have a negative attitude, or look down, we're not reaching our full royal potential. Those who succeed continually look towards their goals.
The saying also keeps me smiling because I feel like it could be used in a really sarcastic way, which is always good for a giggle.
Feel free to share this with the princess in your life.
