I for example, I struggle with rationalism a lot. Because for everything I try to reason with it. A lot of times there are things that I don't know what the Catholic teachings are on them, then I'd just reason with myself (or maybe with God) using logic to convince myself it's a certain way. But then they turned out to be wrong a lot of the times. I have to say having the trad cath AI chatbox helps quite a bit so I can look for answers easier now not just me thinking in my head.
Also I have a Jew in me. I'm very calculated, stingy person that counts on every penny. Growing up I always use pirated content (shows, movies, games, etc.). Now for the games I used to play I actually purchased some of them so that's kind of a restitution. And instead of pirated shows I watch free videos on YouTube for entertainment.
