...I'm Obsessed with Organization...

So I have this weird thing where organizing my stuff makes me oddly happy. Like, I spent an hour arranging all my books alphabetically last night and it felt like the best thing ever. But then today in class, I caught myself staring at a random student's messy desk for way too long, wondering how they live with such chaos... Is that normal? Am I just overthinking this? Anybody else have weird OCD tendencies about neatness?
