I would arrive at mass about half an hour or more to say my prayers out of my prayer book when in earlier days of needing to do so.

My Jars of Clay Prayer -
Create a clean heart for me O Lord,
A humble and contrite heart.
A mind to discern and understand,
Reality and the Obvious.
A Gentle Spirit, Kind and Loving,
Full of Compassion, especially for,
Those suffering, lost and hungry.
Persecuted under cruel affliction.
Not a proud or haughty Spirit,
But a Stern and Direct Spirit.
And a Peaceful and Determined Will.
In Your Holy Name Jesus.
Amen

Addition to the Sacrifice Prayer -
O my Jesus, it is for love of you, in reparation for the offences committed against the immaculate heart of Mary, and for the conversion of poor sinners, that I labour for the kingdom of God, grant me God Speed and your Grace as I journey my road Set before Me, my path of cobble stones, always Striving forward to the Ultimate Goal, never looking back.
Amen

My Sacrifce Prayer -
O my Jesus, it is for love of you, that I labour for the kingdom of God, grant me God Speed and your Grace as I journey my road Set before Me, my path of cobble stones, always striving forward to the ultimate Goal, an extinct evil realm, never looking back.
Amen

My Addition to the Decade Prayer -
O My Jesus, forgive us, save us from the fires of hell, lead all souls to heaven, especially those most in need of thine mercy.
Amen
