Someone made the point that it would take a long time after going through this list. The confession of venial sins in the Confessional is not necessary. HOWEVER, if we desire to grow spiritually, we grow in steps. Early in our walk, we will figure out where we fall often.
By figuring out our "core" sin, the one we return to often, we can eliminate it. This is the purpose of confessing venial sins in Confession - to help eliminate their re-commission.
