Is it really possible to have a complete system?

[supergtdman]

I would argue that I have much more captured and better organised than most people, very likely even better compared to David Allen himself. I can organise lots of data very quickly and with little effort because I have spent a lot of time researching how to do it and set up tools and processes to make it as convenient as possible and automated as much as possible. Obviously David Allen's GTD system itself in isolation doesn't cut it.
I use GTD system but in addition to that I do all kinds of life logging, i.e. I track everything I eat, my health stats data, sleep, excercise, all my expenses, write a journal, capture daily pictures and sometimes videos, etc. I capture most of most of my thoughts and ideas, I say **most** because sometimes I get many thoughts flowing very quickly and it's impossible to capture them all even on audio/video.
You could argue that it's all just "general reference" but in practice you can't just file everything non actionable into some arbitrary categories and organise everything with a single label or whatever as David Allen suggests. That's not going to work. There is much more to this than that if you really want to keep all of the data really conveniently and easily usable. So there are in practice lots of sub-systems to manage every aspect of your life.

My point is that from my experience the more objective data you have and the more you know - the more you realise how much stuff you actually just **don't know** at all. I'm not just a skeptic, I'm a critical thinker, I don't think in black and white. A lot of people here just pointlessly defend the GTD system and whatever.
I'm perfectly fine with GTD the way it is. It's not anywhere close to being complete though, that's all I wanted to point out. Yes, you could say that doing stuff which is not on the lists is also a part of GTD, and call all of it "work that showed up". It's too simple however and that's really just an excuse because not everything that's not on the lists is going to just **show up** and grab your attention at some point. I mean the best thing for you to do in any moment could be something you have no idea about at all whatsoever. It's not going to just **show up**, the option is always there but you just don't see it. I'm not talking about not having stuff like "sip coffee", "eat lunch" and etc. on the lists which don't really matter, I'm talking about stuff which could be life changing.

Anyway all I'm saying is that GTD is presented as something much more elaborate than what it really is by David Allen, all it really is - are just lists with reminders. Those lists alone are not going to give you "mind like water" state. They're not going to show you all possible options of what you might want to do. They can't be fully trusted. They can't be complete. They do help sometimes but that's all.

You could have all of your reminders externalised on the lists and still stay stressed and not know what to do because you still can't have enough data to make the best choice. Sometimes you can't even make a good choice, sometimes you can't solve some critical problems even when you have lots of knowledge, all of the money in the world, lots of experts giving you the best advice they can, and etc. Sometimes you just don't know.
