Make a brief examination of conscience before going to bed at night. Two or three minutes will suffice.
Place yourself in the presence of God, recognizing His strength and your weakness. Tell Him: “Lord, if You will, You can make me clean.”
Ask your guardian angel for light to acknowledge your defects and virtues: What have I done wrong? What have I done right? What could I have done better?
Examine your conscience with sincerity:
Did I often consider that God is my Father? Did I offer Him my work? Did I make good use of my time? Did I pray slowly and with attention? Did I try to make life pleasant for other people? Did I criticize anyone? Was I forgiving? Did I pray and offer some sacrifices for the Church, for the pope, and for those around me? Did I allow myself to be carried away by sensuality? By pride?
Make an Act of Contrition:
O my God, I am heartily sorry for having offended Thee and I detest all my sins because I dread the loss of heaven and the pains of hell, but most of all because they offend Thee, my God, Who art all good and deserving of all my love. I firmly resolve, with the help of Thy grace, to sin no more and avoid the near occasions of sin. Amen.
Make a specific resolution for tomorrow: To stay away from certain temptations, to avoid some specific faults.
