He committed to giving strict attention to one virtue each week so after 13 weeks he moved through all 13. After 13 weeks he would start the process over again so in one year he would complete the course a total of 4 times.
He tracked his progress by using a little book of 13 charts. At the top of each chart was one of the virtues. The charts had a column for each day of the week and thirteen rows marked with the first letter of each of the 13 virtues. Every evening he would review the day and put a mark (dot) next to each virtue for each fault committed with respect to that virtue for that day.
Naturally, his goal was to live his days and weeks without having to put any marks on his chart. Initially he found himself putting more marks on these pages than he ever imagined, but in time he enjoyed seeing them diminish. After awhile he went through the series only once per year and then only once in several years until finally omitting them entirely. But he always carried the little book with him as a reminder.
