I just saw a video telling you how to focus on Jesus by reading certain prayers. There are many suggested ways or methods out there. But you cannot beat going straight to the Lord; it's simple and direct. Your goal should be to attain union with God, beyond merely focusing on him. In union, you get all the support you need from the Lord himself, so much superior than reading books, attending conferences . . . in general, learning from someone else. So go heart to heart with God and not let anything stand between you and God, and he will reveal all his thoughts and ways to you. This is the endearing and most efficient way of knowing God. In a way, you don't have to do anything to know him. Like Mary the sister of Martha in Luke 10, just sit at the feet of Jesus and listen to him speak.
