"There is no one who, if he just thinks about it a little cannot find very good reasons to express his gratitude to God." (St. Bernard, Sermon on the sixth Sunday after Pentecost, 2.1) Here is an exercise to do. Write down on a sheet of paper all the things you are grateful to God for. Then on Thanksgiving Day during a time of prayer, offer these thoughts of gratitude to God. Then every night afterwards, before going to bed, express your gratitude to God for his many blessings that day.
