I keep my Areas of Focus as a hierarchical outline of major areas and then within that roles. so my 2020 AOFs are:
Family and Friends
Health and Fitness
Sheep Flock & Farm Management
LambTracker/AnimalTrakker Programmer
Archivist
Household Management
Personal Growth and Development
Community Involvement
World Traveler
and within the Archivist AOF I have several roles, Family Archivist where I do projects like my scrapbooks, genealogy and my huge photo scanning and cataloging project for all the print, slide, negative and digital images in my family. Another role is North Fork Historical Society Archive where I have projects like scaning the collection of women's Club scrapbooks fromt eh early 1900s and the project to scan and catalog our collection of 1500 glass plate negatives. Other things that arein Someday/Maybe include scanning the old prints we have and a full inventory of the museum's collections which has never been done.
I review my AOFs quartery by at least reading them and then do a major rethink annually. I keep them in a DEVONThink note as just text files but I do use indentation to show the hierarchy and color so I can find sections easily so they are not plain text but rich text. I tried mind maping but I donto think graphically and I found all mind map SW I've tried to be frustrating and I went back to simple outline type files.
