Answer the Universal Call to Holiness.
Pray the Liturgy of the Hours
Daily Mass
Frequent Confession
Pray the rosary (I prefer in private or with other Catholics) that means meditate on the mysteries, not just say the prayers but say them from the heart.
Seek example of Saints. St. Francis, “preach the gospel always and when necessary use words”.
Study Scripture & memorize some scripture but understand in context of Church teaching (CCC). St. Jerome, “to not know scripture is to not know Christ”.
Read the early church fathers (some in the Divine Office)
read the didache - Chapter 2 see what it says about abortion.
Little things like that solidify the faith in oneself. But most of all be charitable even to those that hurt you.
“faith, hope and love…but the greatest of these is Love”.
