orgmode and text-only approach
In case you look for a digital approach rather than analog way, offering enough flexibility, I strongly recommend
OrgMode, basically this is a "major mode" for the
Emacs text editor.
Using Emacs can sound scary to some, that may have experienced it as developers, because of its learning curve (extremely powerful, extensions via modes like orgmode..., but so many features, with so many shortcuts), and Emacs is often seen as a text editor for coders only.
but:
- Orgmode made it a really impressive tool as: planner, outliner, markup language (export to pdf through latex, html), capture tool (remember mode), clocking tool, blogging tool and so many other options.
- It is text-only, so will continue to be accessible in many years, can be loaded/edited by any text editor on any platform, even when you don't have Emacs installed, no compatibility, conversion, migration issue you can faced with proprietary issue.
- OrgMode author (Carsten Dominik) is just brilliant, you can have a look at his talks on OrgMode, I especially recommend the one given at Max-Planck Institute at Coln early this year.
- A great community (you can browse the mailing list on Gmane to get an idea)
- Myself i am working on Windows platform where Emacs is supported (easy to install version), but Apple users have a version adapted to their platform called Aquamacs
- Concerning Emacs for non-programmers, I recommend the reading of Emacs for Writers by Randall Wood
- Free Iphone app for OrgMode called MobileOrg available, and I think Android one is on the way
- Extension is available to integrate OrgMode with Toodledo
Last still concerning the text-only format, it makes it extremely portable (Windows at work, Mac at home, phone on the way...), combined with synchronization tools like
Dropbox you just get ubiquitous capture tool, info in the cloud, and can also be edited anywhere with just a notepad.exe (or text editor in your cellphone) when not connected to the internet and sync'ed back later...
Now an easy trap where to fall (basically the same as the quest for perfect tool for GTD that will never end), is once you decide to stick with one (let's assume Orgmode and text-only format), to spend too much effort on the customization of the tool (and believe me it can be really huge) rather than doing things, so for this I would say:
- once you managed to apply GTD in the analog world (pen/paper based) and you need to digitalize it given your computerized activities
- try to strictly adapt the pen/paper approach to the text-only format as a start, previously you had something working, no need to reinvent the wheel, use OrgMode to improve it, automate some parts, and it won't work if the process isn't yet clear for you (if you haven't practice GTD in the analog world successfuly for some time)
- then have a look at few blogs on using GTD with Orgmode, Charles Cave has a really nice one, later you can also have a look at this one called "My Life in Plain Text is really huge not specific to GTD, but goes really in details in what can be done with OrgMode.
