Aside from the obvious (frequenting the sacraments and regularly examining the conscience) I’d highly suggest the book Way of a Pilgrim, which discusses the use of the Jesus Prayer (it varies, but generally comes out as something along the lines of: “Lord Jesus Christ, Son of God, have mercy on me, a sinner”). That prayer, used for prayer of the heart (contemplation) is absolutely phenomenal! You can pray it anyone, without any aids or having to keep track of anything. All you have to do is bask in the glory of our risen savior!
After that I’d suggest readings by one of the great saints with whom God has chosen to bless us. Anything from the desert fathers of the early Church to the early Western monastics (remember, Roman Rite Catholics and Eastern Rite Catholics - and Orthodox Christians - can be helpful to each other due to our shared beginnings) and recent monastics and popes can be extremely useful. The most important thing is to learn how to pray, how to open your heart to Christ, and how to let him lead you. It’s not about learning how to do something, it’s about learning how to let Christ do something in and through you, by the power of His grace.
In Christ,
Stephen
