Each system with unique purpose
I have to chime in to agree with everyone - one system is better. I had several before and all it did was confuse me (where did I capture that?) and you end up not trusting it. I kept creating additional systems to track the systems and it was a mess. One is always better.
That said, if you have to have two or more, each needs to have a specific purpose - business and personal, as an example. If you immediately know which one a task should go into, you are doing ok. And you will have to review both, of course.
I completely agree with Dena on software. I pick it based on how much I like to interact with it. If I like the design, I will be interacting with it. If it is boring, I will never open it again. Shiny objects, I know. :)
1 system, but different lists
I have one system, in the way that I follow up private projects and next actions in the exact same way I follow up work related projects. But I do have them on two dofferent lists. I do my follow up in an excel sheet, this only means I have a different tab for my private actions. Same system, different list.
You might call this a subsystem or a different system... I call it a different face/aspect of the same system. Looking around you, you will find a lot of that type of different faces your system can have. Yet it is still one system...
- Your dirty dishes lying in the kitchen sink = "these are for cleaning"
- a pile of bills to pay in a fixed location = "these are for paying"
I don't know if I'm clearly expressing myself, what I meant to say was: keep them totally integrated or on separated lists as you prefer, but make sure they follow the same philosophy and approach...
Another country heard from...
My situation is slightly different, in that I have my own business and other "work-ish" activities I'm involved in, but also have a strictly 8-5 "job." I have the issue of not being able to have one system due to IT constraints at my job. I have no input (other than the very occasional idea that comes to me after hours, which I just email to my work email) related to work unless I'm at work. I don't even need context lists for my next actions at work. Just one action list, a waiting for, someday/maybe and a project list.
I have my "everything else BUT my job" lists accessible on my iPhone, and I always have capture tools for when I have "personal" ideas at work (or anywhere else). I have NO problem having these two systems, but I will admit that I'm probably in the minority as far as having such a dividing line between my work and personal life.
