Like most, I get distracted during prayer too. I just try to do what I read many years ago, I think it was from St. Therese, who also got distracted during prayer. (I think I remember reading that she had trouble meditating during the Rosary.) Anyway, the advice was to just try to pray about whatever is distracting you. If someone comes into your mind during your prayers, pray for that person or whatever situation you’re distracted by. Just try to bring everything under the umbrella of prayer. That’s what I do and it really helps. The one thing you don’t want to do is get angry with yourself. We are very weak creatures and God knows that. Just calmly bring yourself back to focus even if it is 20 times that you have to do it during one prayer session. And don’t forget to ask God to help you focus.
