In a few sentences I walked her through the core of GTD:

- Collect and download everything that’s got your attention, especially the stuff you’re holding on your mind.
- Decide the very very next action you need to take on any of those.
- Organize it into a few key buckets:

a list of your outcomes (Projects)
a list for the things you need to do (Next Actions)
a list of things other people owe you (Waiting For)
a list of the things you might like to get to (Someday/Maybe)

- Look at it all on some kind of regular basis to make sure it’s still current (Review)
- So that you can always trust you are making the best choices (Do)
