Those who keep a book of remembrance are more likely to keep the Lord in remembrance in their daily lives

"Please follow the counsel you have been given in the past and maintain your personal journals. Those who keep a book of remembrance are more likely to keep the Lord in remembrance in their daily lives. Journals are a way of counting our blessings and of leaving an inventory of these blessings for our posterity."

- Pres. Spencer W. Kimball, President of the Church, "Listen to the Prophets," General Conference, Apr 1978
