I think that it is not a very good idea to lump into one daily time allotment one’s reading of the Holy Scriptures, of other religious literature (including works of apologetics), and prayer. For myself, for many decades, I have set aside time for prayer and for reading the Bible, but I have not included other religious reading in that time. It is not necessary to read apologetics every day. One’s reading, religious and secular, should be varied. I include apologetics in my reading, but I alternate books of apologetics, theology, church history, etc., with other books (non-fiction, novels, poetry, and so forth). Reading the same kind of thing (apart from Holy Scripture itself) every day can lead to growing tired of something, apologetics included. Just be sure that your reading includes apologetics among other subjects, and be sure also to pray and to read the Scriptures daily, whatever else you also may be reading during the day.
I begain reading apologetics seriously when I was in my late teens, while a sailor in the U.S. Navy. I read mostly Anglican apologetics (works mostly of an “Anglo-Catholic” orientation) at that time (and such Anglican works, by the way, can be very helpful in defending many Catholic questions), as well as some Roman Catholic, Protestant, and Orthodox books of apologetics and theology. It is not a waste of time to read non-Catholic works of theology and apologetics. For one thing, is is very important to understand what non-Catholics think, and how they reason, about their faith, whether they are Eastern Orthodox, Protestants, sectaries, or non-Christians (Muslims, Mormons, whatever). Many apologetic works, Catholic and Protestant/sectarian, treat non-Christians unfairly, misrepresenting their beliefs and practices. In the same way, Catholic and non-Catholic Christians write much that is not really true about each other. Too often, writers try to “score points” in debates rather than to come to grips with a different faith perspective in order to convert the other, not merely to win in debate with him or her.
However, be sure that you are strong in your own faith before getting into apologetics, especially in reading non-Catholic works of apologetics or non-Catholic religious works generally. It is easier than a Catholic might think to begin to reason as the Catholic’s “adversary” does!

Approach apologetics systematically, not getting too deeply into difficult questions before one is prepared. When engaging in apologetic discussions with non-Catholics, send up quick prayers periodically to our Lord and to the Holy Spirit. One should be doing such things in prayer and humility.
