As some has already said in this thread, I enjoy living parasitically, hedonistically and insatiably curious.

by TurncoatIt's sort of a compulsive thing.
I often need to dissect things down into smaller details to become comfortable with it as a whole. I follow my diet by the calorie and nutrient (I've been lazier about it lately, but I still keep shorthand notes on pads of paper related to what I'm eating, mentally estimating my intake at the end of every day). I prefer to keep everything in a nice, clean grid, to promote cleaner thinking that isn't disrupted by clashing clutter and organizational disorder. I manage all of my plans with itineraries in the form of constantly updated notepad files, ones that may reference other notepad files that further explain my own notes. Before talking to someone I know fairly well in real life, I'll try to map out the likely conversation paths that will occur based on context and who they are, then weigh response likelihoods to my own possible responses, all to judge how possible conversations might go in advance. Often times I'll plan for something that's never even discussed.
TLDR; I kind of can't help it.
Everything you wrote is what all of us do subconsciously.
lol, I certainly don't. I just go with the flow and whatever happens, happens.
What turncoat does is pretty extreme in my opinion.
You could be my evil twin, that's the exact opposite of what I do.
I have a slight eating disorder and I'm eating everything that's infront of me, as long as it's food. On the other hand I tend to lean for healthier options and I almost never buy junk food.
I clean my house when it looks untidy and over-all I keep things clean but organizing papers in a neat order is the biggest pain I can think of.
I use the meetings feature in my cell phone to remind me of meetings I'll otherwise forget and usually I rush to them on a 15-minute-notice. Otherwise I'll go pretty ex-tempore on everything.
I don't plan any interactions. Isn't that kind of difficult, anyway? I tried to give a speech by remembering the stuff by heart back when I was in upper secondary and it didn't really work out.
If you learn how to not get obsessive about perfection, perfection can be your best friend 
Whenever you do something, you will do it just right, as long as you can be sure it doesn't take too much out of you, which means you must not get obsessive about it. But you need to have the mentality to indulge in the activity and you need to see where perfection is!
Best part is, it takes boredom away! Especially if you finish your activity!

That usually just leads me to obsess over not obsessing.
Perfection is sought, never achieved. There is no "perfection" that isn't just an ideal. Anything regarded as the best will either be outclassed or outdated with time.
"Just Right" is simply the layman's perfection.
"Best part is, it takes boredom away! Especially if you finish your activity!"
No "activity" is really finished, just divorced from. There are always ways I can make anything I do better.
"If you obsess over not obsessing then you have failed! And that's unacceptable!"
Yes, precisely why it's a problem to focus on it too much.
Vicious cycle! 
"An activity is finished when you decide its time :)"
Much like making a decision at the flip of a coin, once I say it's "done" I'll wish I hadn't.
And then I'm usually not.
