Area of Focus in OmniFocus2, vague or specific

Alex Hu

I feel confused for the set up of AoF folders in Omnifocus. For example, I previously have a folder named Professional Development, and under it I have another folder called "Becoming a professional translator" under which is a project named "Pass the CATTI certificate". But when I do the weekly review today, I come up with this idea of using "Becoming a professional translator" as the AoF folder. So if I do so, is it still an AoF, or a future goal in the GTD system?
