We absolutely do not have to believe or accept any private revelations, even those approved by Holy Mother Church. We must only honor Mary under titles given to her on the Liturgical Calendar, such as Our Lady of Lourdes (an optional memorial), Our Lady of the Rosary, Our Lady of Good Counsel, Our Lady of Guadalupe, and Our Lady of Fatima and so on. The primary title of Mary in the Liturgical Calendar is Theotokos, Mother of God, a holy day of obligation in some countries.
We absolutely must know doctrine and dogma and understand the basic definitions in the Creed, which is explained in the CCC.
I hope you are not wasting time on things which are not required at the expense of things which are.
We must pray daily. And, we are highly recommended by several popes to read the Bible daily and try and partake in the daily reading of some of the Divine Office.
Do you duties first. Meat first, dessert second.
