Could be as trivial as a type of food, a TV show, or something more serious.
I’m the same way. I just had to keep trying to figure it out, and eventually something clicked. I’m still bad at doing math in my head, and I found out that different types of math math more sense than others. Like I’m really bat at algebra and calculus, but I can get geometry and trigonometry. It just took WAY more practice for me than other people I know.
