Naps are one way we can gain rest.  I had noticed from the events of the past week that I was very mentally tired.  So today I dedicated the first four hours to getting rest.  It is a Saturday, so there is no reason why I should not rest.  More importantly I know I need be rested before Monday comes and I am again spending emotional and mental energy to help others.  I encourage you to listen to your body and when it is crying out for rest, please find time to give it the rest you deserve.  Running on empty is not good in a  car and it is no better for us to try to run our bodies on empty.
