One of the best ways to get more spiritual fruit from confession is to make a brief examination of conscience each night before bed. A brief look over the day, to give thanks to God for His grace that helped me to do good, and to express sorrow for the times I sinned, is enormously helpful. Then, when I do get to confession, I’m better able to see the areas of my life where I’m still habitually sinning, even if it’s “just” venial sins.
