I think we all know that at times, emotions simply ARE and you not only can you not "choose" to change them, but you shouldn't. There's a time to mourn, a time to feel sad, a time to be angry and even bitter. But I think it's also empowering to discover that not only is it healthy to experience that emotion, you also have the ability to choose to move on, and I think that's what "happiness is a choice" is all about. It's also an action. It's finding the way to build a new, different happiness from the one you dreamed of into your life and move forward.

Not always easy, but considering the other option....
