While far from perfect, this is what I have done. At the suggestion of Meg Gott (GTD coach) I made a list of my areas of focus and responsbility. It was very hard to determine the degree of specification, so some were pretty geneneral (My Health) ands some were pretty specific (Smell Patrol: Manage and Monitor all sources of household bad odors- refrigerator, trash, basement humidity, lunch boxes). Then I made each of these AREAS into a category in "TO DO". Then the projects are listed in these categories and then they are written as if they have a tangible successful outcome. So under MY HEALTH are projects such as "My weight is optimal for me", "My lab tests and diagnostics are up to date", "My schedule is fine tuned to limit stress". Within any area of focus or responsibility, I have a few SomeDayMaybe projects, such as "I have a couple of social sports that I enjoy. Under the area of SMELL PATROL I have these projects "Refrigerator is Clean and Easy to Find things in", "Garbage goes out night before day ". These projects gave rise to checklists or Next Actions in different contexts. For Garbage, I needed to ensure sufficient bags, so that became an errand. For Frig, I needed to do some brainstorming. That itself became a N/A and from that came another N/A--start a soup pot and while amking dinner do a search for recnt leftovers and add to it and reboil while I am cooking. And, a checklist item "Sunday-toss any leftover soup, unless athe whole thing is fresh within 2 days. From that came another N/A "put masking tape and marker in kitchen drawer to date leftovers". I hope this helps you see the paradigm. My suggestion is to keep reading and re-reading the book and fine tuning your system. And, don't try themes and variations until you master the original score.
