Don't worry be happy
I am going to share with you one of the first things I ever really learned about myself. I have no idea if this applies to anyone else. I learned it after several weeks when I was really done because of something that happened. I looked back and my life and realized something really simple. I am happy when I choose to be happy. I am not saying I have control of instantaneous emotions in response to something. But if I am still having that emotion three or four days along I am choosing that. Held emotions are my choice.
