Hi there !
I'm french, and I've discovered GTD a few weeks ago. Before trying to apply it, I was looking for a unified solution for all those to-do's. Then I discovered Evernote, and many ways to organize Notebooks and tags, including the famous "The Secret Weapon" that has been indicated sooner.
As many others, I believe that both GTD and Evernote are tools, that has to be configured for the convenience of each user. And I also believe that the more suggestions can be found, the more ideas for tuning there will be !
So here is my own organization, as it is now. I really appreciated TSW, but I thought that if each note has to be set with a ".When" tag, and only one, why use tag ? So I began to tune TSW my own way, to this result :
@Inbox (default notebook, where all my new notes go)
Actions pending (a notebook pile) :
!NOW (actions I have to do today)
1 - Daily (actions that I have to do daily)
2 - Tickler (actions with a date ; all of them start with YYYY-MM-DD + keywords)
3 - This week (actions that have to be done first)
4 - Next week (actions that have to be done next)
5 - ASAP (actions that have to be done later)
6 - Someday (actions that I might do one day, but not for now)
7 - Waiting (actions that are waiting for somebody else to act)
Done (actions that are done)
Active Projets (each note in this notebook is a checklist with the different steps of the project)
Notes/References (another notebook pile) :
(notes are saved here with one notebook by theme, alphabetically ordered, eventually splitted to avoid too many notes in one notebook, so I have a Contacts Work notebook, a Contacts - Girls notebook, etc.)
My tags are TSW-inspired : What, Where, Who, and associated sub-tags. I use different symbols for each type : @ for the Where tags, + for the Who tags, - for the What tags.
I use tags mostly on my Androïd phone, because it's much way easier to navigate through, but I use mostly notebooks on my computers and for review
Daily, I review my actions pending, and move notes from one to another Actions notebooks if appropriate.
Weekly, I review all my notebooks but Notes/Reference, create new items, and organize them.
Hope it gave you some ideas
