I'm soooo the same way! I have a system for each topic I'm studying and I stick to that system because its earned me a 3.8. I've had friends make remarks about me being a perfectionist, and they're probably right.
My perception of the situation is this: we all have the capacity to be depressed,OCD,or victims of any other disorder. By definition, any activity that keeps someone from living a 'normal' life is a disorder, and is considered unhealthy. But if we want to over-achieve and have developed a system of accomplishing just that, then the success is a product of the system we designed. That's not unhealthy....that's an accomplishment!
I look forward to reading more of your posts...I feel like we have a lot in common and you've yet to convey a negative connotation.
Take care
