Possibility lies beyond fear.
"This might not work."
~ Seth Godin
When we are too afraid to let go of what was, or what could have been, our actions get driven by fear and insecurity. The child parts in us take over and they seek certainty because for them this is all about survival. For them "this might not work" is a threat.
But, if we are courageous enough to let go of our need for certainty, if we are able to mollify the child parts through love and compassion, if we are able to take charge as our adult selves, we make space for love and possibility.
Once we understand that our survival is not at stake, we can start living, and we can embrace the "this might not work" mindset.
