Invariably during some of the Ave Maria’s of the Rosary we let our minds wander, and the only thing keeping us on track is the movement from bead to bead at those times when suddenly there is a space in the beads that returns our awareness.
What is that awareness that comes back? Hopefully that we realize we are addressing a real person (perhaps at that point we should apologize to that person, Mary, for losing sight of her in our speech).
You may want to use your rosary in continuing your Gloria Patri’s, to insert breaks like that to remember who you are talking to, Father, Son, and Spirit. Throw in an apology or two when needed.
You do not have to examine the theology of the Trinity when praying this, it is a Blessing of God by declaring a blessing of “Glory” onto his Name. It is a shout of joy, which you now feel because he helped you have a good confession. “The Father helped my, Glory be to the Father!!!, The Son helped me; Glory be to the Son!!!, The Holy Spirit helped me; Glory be to the Holy Spirit!!!” That’s all the deeper you must go, just being happy you know these three persons and that they come to your aid.
You made what was a steep promise because to show God how seriously you wanted this good confession. He did not help you to get 150 prayers a day, not because of a bartering with Him. He would help you without any promise, yet he also saw your earnestness and your desire to renew your friendship with him. That is what he hopes to see in those who turn to him, and he loves to help them.
Try using the Rosary beads as a counter, to keep your focus, but focus on words of simply gladness about him being your God, who helps you.
