You must be the change you want to see in the world, as Mahatma Gandhi so eloquently said. In other words, change has to start within ourselves; we cannot expect the world to change if we do not. Instead of focusing on the problems, we can start to live the solutions.
However, the stress most of us are dealing with is not from life-or-death situations, but is the distress that arises from an accumulation of pressure from much smaller issues. And although each separate incident may appear benign, if our response becomes increasingly stressful and we are no longer able to maintain our equilibrium then the body will put out the red alert.
