Step Ten is not about maintenance, because there is a rule in our universe that nothing ever stays the same.  All living matter is either in a process of growing or in the process of regressing.   Up until now, if you followed the first nine steps with an honest heart and the direction of a Higher Power, you will have grown considerably.  If you do not keep growing, you will start sliding back into your old behavior patterns and ways of thinking.  As you may now realize, spiritual growth is an experience so precious and valuable.  As with the preceding nine steps, the Tenth Step is one more power-tool to help you succeed during the day.
