1. In every prayer you say, every Mass you hear, every Communion you receive, every good work you perform have the express intention of imploring God to grant you a holy and happy death and no Purgatory. Surely God will hear a prayer said with such confidence and perseverance.You can read the entire list of Father Paul O'Sullivan's list here
2. Always wish to do God’s will. It is in every sense the best for you. When you do or seek anything that is not God’s will, you are sure to suffer. Say, therefore, fervently each time you recite the Our Father: Thy will be done.
3. Accept all the sufferings, sorrows, pains and disappointments of life, be they great or small, ill health, loss of goods, the death of your dear ones, heat or cold, rain or sunshine as coming from God. Bear them calmly and patiently for love of Him and in penance for your sins. Of course, one may use all his efforts to ward off trouble and pain, but when one cannot avoid it let him bear it patiently. Impatience and revolt make sufferings vastly greater and more difficult to bear.
4. The greatest act in Christ’s life was His Passion. As He had a Passion so each one of us has a Passion. Our Passion consists in the sufferings and labors of every day. Therefore, let us do our work, accept its disappointments and hardships and bear our pains in union with the Passion of Christ. We gain more merit by a little pain than by years of pleasure.
5. Forgive all injuries and offences for in proportion, as we forgive others, God forgives us. Go to confession. This sacrament does more than “just” rid us of our sins; it gives us a tremendous increase in sanctifying grace. It wins for us a higher place in Heaven, with increased union with God. Each time we go to confession, we are preserved from many dangers and misfortunes which might otherwise have befallen us. A devout confession helps us to hear the inspirations of the Holy Spirit, and to hear and follow the advice of our guardian angels.
