The daily examination of conscience is an ancient Catholic practice. It's very simple, and it's designed to help us identify our sins and weaknesses so that we can improve and grow stronger in the spiritual life. Basically, it consists in taking a few minutes at the end of the day to prayerfully review our actions in the light of God's commandments. The Act of Contrition is often said afterwards. The daily examination also serves as an excellent ongoing preparation for regular Confession.
