Often, if we allow our thoughts to race ahead of us, if we start to worry or obsess about potential consequences, we find that we often become the victim of our self-fulfilling prophecies. We worry too much about potential outcomes, and subconsciously our actions start to take us in that direction. It is not a coincidence. Our mind has an incredible capacity to lead us to action, to guide us towards outcomes.
But it works both ways. All too often positive thinking begets positive outcomes and negative thinking leads to negative outcomes.
