Are any of you "perfectionists"?

I'm constantly called a perfectionist. It's almost like it's used as an insult though when I get comments such as, "don't be such a perfectionist" or "It's unhealthy to be that ****". I don't think I'm a perfectionist per se, I think organized is a better word for it. I make a lot of lists, I organize and then reorganize, and I get anxious when things aren't "perfect" or when I'm overwhelmed with my lists. For example, I would re-write my notes if my handwriting bothered me, I tab everything, and I color code everything. My professor said it's unhealthy but I just don't agree. What's wrong with being organized? It's just the way I learn. I have to do my system in order to learn and get everything done that needs doing and as long as I am getting done what I need to and learning then what is the issue? Are any of you like that?

Let me know if I should post this in a different section
