Worry is a habit

Worry is a habit.  It wastes energy.  A trite saying is 'don't worry, be happy'.  For chronic worriers, this would be something else to worry about.  A more useful way to deal with worry is the following:  there are events in life over which we have control.  Since we are in control, there is no need to worry.  There are also events in life over which we have no control.  Since we are not in control, there is no need to worry.  Worry is therefor needless as well as wasteful of energy.
