Treat happiness as an action verb. Choose to be happy. No one can make the choice for you or do anything that can make you happy. It is all up to you and your choice.
We are created to be happy in this life and the next. However, happiness will not present itself to us with a large pretty shiny red bow. Even if it did, we would have to open it and decide that it was our gift, no mistake, and it was perfect for us, and we would have to decide to accept it and be happy with it.
All that happens is for a reason. We are meant to find our joy, our happiness hear on this earth. Happiness is more than a feeling. It is our choice, our recogniton of the gift given and even more of the giver of the gift.
