There's a lot of routine in my life, but I've noticed I don't quite perform those routines like a robot would. I often perform the steps out of order, not by design (because there's usually an optimum order for the steps), but by accident. It doesn't do any harm usually, except that it annoys me that it can't have been fully optimised.
I like routine because when I get used to it I don't have to think about it, so my mind is free to ponder more interesting things. As long as the environment doesn't change. No wonder I don't like change. It's like when something's out of whack with a robot system that spray-paints cars, e.g. the car is in the wrong place, and the robot carries on regardless, just spraying the wrong parts and making a complete mess. Unlike the robot I notice things are wrong of course, and then I get upset because a task that should be very easy is suddenly rather more demanding - I have to think new thoughts, and I don't know whether I can adapt to the change or not. I'm at risk of failure with something I'm used to succeeding with.
But I'd hate it if my entire life was nothing but routine, even if the routines were perfectly designed. My brain needs challenge, it needs to trailblaze, to look for new ways to make my life more comfortable and more fun. Even non-productive challenges can satisfy that need, to a degree at least. Just that I'd rather such challenges were confined to particular stages of my day when I'm ready for them, not breaking out unasked for during the monotonous chores I have to do, such as acquiring and preparing food, maintenance of personal hygeine, etc. I dislike having to do those things at all and I don't like setbacks.
Pretty much the only pleasure I get from doing routine chores is the feeling that I've made them super-efficient so that I'm getting them done with the minimum of fuss and bother thanks to my own ingenuity. Though there's also a certain pleasure in the sheer rhythm of a good routine. And it's nice to go through the steps of a routine and find I've learned to do it more elegantly than I did last time. I like acquiring skills. I hate the pain of it, but I like getting to the point where it's paying off.
The most important part of my life to me is the non-routine, creative, new part of it. If there was a machine that did all the other stuff properly I'd be onto it like a shot. But maybe I should be careful what I wish for. Maybe I'd miss the mechanical chores if I completely got rid of them. It just doesn't feel like I would because I've never been rid of them.
