Glad to inform and inspire, man! :D

It seems to me that you are excited about the concept of the GTD system, but may need to ease into it, to avoid going cross-eyed and throwing it out the window. If you’ve never entertained the notion before, it can be a bit overwhelming — I’d recommend getting a hold of the book and/or a recording of a David Allen seminar before committing yourself to it.

That said, the core concepts are pretty straightforward:

– Set up an inbox that it’s easy to enter things into
– Set a standard daily processing time for those items
– Set up context folders/buckets/notebooks/tags/other-metaphors that you can place next actions into
– Set up an active projects list that’s easy to refer to
– Set up a reference file system to get things out of your way that you may need to look at later (reduce clutter)
– Set up a someday/maybe section for things that you aren’t ready for but can’t throw away
– Set up a tickler system to remind you to look at things that need a poke now and again, but don’t necessarily fit into next actions right now
– Set up a standard weekly review to monitor the health of your system and tweak it

I would suggest getting it worked out on paper first, but Evernote is basically a paper system that is accessible anywhere, and searchable. As such, it doesn’t have some of the niceties of an automated task system — no calendar integration or reminders, for example. If you are used to a paper system, this is fine. You will mark things on your calendar, or set up a rotating tickler like I did. If you need something with reminders and calendar connections, however, I would suggest checking out my GTD in Springpad or GTD in Producteev posts, or some of the 40Tech reader workflows that use iPhone apps that connect with Evernote (use the menu up top or search ‘reader workflow’ to find them). Producteev has a desktop app on the way, as well as an official Android app (Astrid is the app to use for now), and Springpad uses HTML5 to sync for offline use on mobile and Desktop.

Also, I should mention that this post was written in 2009, before Evernote introduced Notebook Stacks. You could, feasibly, set this up in multiple notebooks and organize it well, visually — but keep on mind that tags can be used across notebooks (and be filtered by them), and that stacks are not visually supported in mobile apps as of yet (iOS, anyway, not sure about Android).

Hopefully, this helps you get started in the way that best suits you. If you have more questions or need help, please feel free to respond here or in the other posts’ comments, or email me directly. :)

Cheers!
