Trying to apply this lately…

Go in all simplicity; do not be anxious to win a quiet mind, and it will be all the quieter.  Do not examine so closely into the progress of your soul.  Do not crave so much to be perfect, but let your spiritual life be formed by your duties, and by the actions which are called forth by circumstances.  Do not take overmuch thought for tomorrow.  God, who has led you safely on so far, will lead you on to the end.  Be altogether at rest in the loving holy confidence which you ought to have in His heavenly Providence.
~St. Francis de Sales
