Anyone have any tips on memorizing information?

Honestly- I can’t just focus on what videos say sometimes. My brain’s all over the place, annnd- I’m about 97% sure I have ADHD. So it’s hard for me to focus. Sometimes, it’s not because I don’t want to. It’s because my brain wants to listen to distractions and can’t continue on what I need to. And I just suck at memorizing. I feel like I really need to focus, but then it feels more like I’m forcing myself. And I don’t like that. I’m trying to make it fun to make it- ya know, more like a more FLUID occurrence instead of trying to drag my brain away from distractions like a distracted dog your walking.
