Do you believe happiness is a choice?

All things are a choice, even down to those things that science considers genetic.  As infinite beings we chose to inhabit this frame of reference in the body that we are in, thus all things are chosen by us at some level.  It all depends on what frame of reference you look at it from.

As we are the Elohim (Gods and Goddesses) refered to in Genesis as the creators of this reality, we started the code that runs through every action of every being inhabiting this construct.  We have simply chosen to be consciously aware of this particular point of view, what many call the 'individual consciousness'.

With this as a base reference point, it is easy to see that we have made every choice in our lives.  Happiness is a state of understanding that we are perfect as we are, and thus living our lives to the fullest potential we can.
