You must change your circumstances when there appears to be no immediate reason for doing it. You must follow an inner urging and an inner direction, without really understanding what is happening and what your future or the outcome will look like. If you do not have the strength or courage to do this, you will just stand where you are, becoming increasingly full of anxiety and confusion, increasingly worried, increasingly frustrated and compulsive until your circumstances just fall away and erode your life, like a person who is standing on a slowly shrinking island or in a boat that is taking on water increasingly.
