When you think you have total control of something it’s often slipping right through your fingers. The harder you make a fist to keep it the faster it slips away.
I think most of us just want stability in our lives and we often sacrifice the things around us and stay stuck in our ways to keep it that way. Change and risk while not always great at least has the opportunity for better times ahead. In an uncertain world thinking we have control often puts the mind at rest enough to at least get some sleep at end of the day.
