Talking to a priest will probably yield better advice than I am able to give, but here are my ideas anyway.
Much depends on your general temperament. What works for one does not necessarily work for everyone.
I get a lot out of spiritual reading. The foremost spiritual reading is, of course, Scripture. The Church has the ancient way of reading through Scripture called
Lectio Divina. That’s a great way to do it.
There are all sorts of other spiritual classics out there as well. As you already experienced, you do have to be aware of where you are at. I recall picking up St. John of the Cross’ “Dark Night of the Soul” when I was fairly new to the faith. I couldn’t make heads or tails of what he was talking about. I wisely set it aside rather than trying to force my way through it.
I think “The Imitation of Christ” by Thomas a Kempis is a great one. Lots of short meditations that have loads of depth. There is much to reflect on.
I also really like
Divine Intimacy by Fr. Gabriel of St. Mary Magdalen. From the looks of it, it may be out of print, but maybe you can petition TAN Publishing to bring it back.
Above any recommendations of books and/or devotional practices (and this is where a priest would come in handy), I would encourage you to spend time reflecting on why you feel that daily Eucharistic Adoration and a daily rosary are “not enough”. I think that is the discernment that will help the most rather than devotional trial-and-error. You may find yourself never feeling like it is “enough”.
Sometimes, Satan attacks the faithful by making us always question whether our efforts are “enough.” That’s not hard to do considering nothing we give God will ever be enough to earn our salvation. If he cannot stop you from praying, Satan will try to poison the experience. Whatever time we spend wringing our hands over not doing enough is going to make the devil happy. Such thoughts often keep us focused on ourselves and they sap the joy from what prayer time we do give to God.
But it could also be an interior thing. Maybe with these devotionals, you feel yourself going through the motions without really “connecting” to Jesus. That could also lead to feelings of not doing enough because the practices aren’t leading to a deepening of the relationship – which is their ultimate purpose.
A priest would be a helpful guide in figuring out which category you fall in (or perhaps some other category I am not thinking of at the moment).
