I'm having a bit of trouble understanding how to fit these into the GTD system. I've read through the pages in the book, but it just hasn't "clicked" for me yet.

What extra information do I need to define for these areas? It seems like if I define NA's and Projects, I've also defined 10K and 30K?

It seems like they translate into 1) "Now" items 2) Short term goals and projects and 3) long term goals and projects. If that's true, then why did we complicate it with all the other stuff, and if not true, what am I missing?

Thanks!
