The productivity consultant Tiago Forte has a method of organising digital information that I have used for a while personally and find very useful. It’s described in great detail on this page on his firm’s website, built his interview to Evernote describes it succinctly:
I have this method I’ve developed called PARA, which stands for projects, areas, resources, and archives… PARA is 4 categories, and that’s kind of the starting point. You divide your work into projects, which I’m using here the GTD definition, a series of tasks linked to an outcome.
Areas of responsibility: Some standard or area of your life that’s an ongoing concern; that you want to maintain on an ongoing basis.
Resources: Basically, interests or topics. Things like website design. For me, it’s not a particular project — not even really an area because that’s not my work — but it’s something I’m interested in that I’d like to keep track of.
And then Archives, which is anything from the previous three categories that’s no longer active, because you want to avoid clogging up your actionable categories. As soon as something is not top of mind, not front and center, you want to move it to the archives, but still keep it in case you want to go and find something there.
– Tiago Forte’s Approach to Productivity
It’s practically, and as he describes, is a framework replicable across your toolset: your task manager (say Microsoft Todo), your notes capture system (say Apple Notes) and your research + organisation system (say Evernote).
