let each person take an accounting of the things he has done during the day and during the night and, if he has sinned, let him stop. If he has not sinned, let him not boast.
Let this system of observation assure us of not sinning: let each of us note and write down his deeds and the movements of his soul as though we were going to report them to each other.
...If we write down our thoughts as though we were going to report them to one another, we will keep ourselves very far away from filthy thoughts, ashamed as we are to have others know about them.
Anthony the Great in his Life
