If you use a checklist for routines separate from your calendar and action list. When do you check it? How do you integrate it?
DA says he checks his calendar first, then action lists. It seems like routines sort of fall in between.
So you'd go calendar-->routines-->action list
Of course, some routine or recurring items could go on your calendar.
I've said before but I'll say it again, it seems like DA is not very clear about integrating routines/structure with projects/actions. Not everything is a project or needs to be done at specific time. Seems like we need a couple more categories (and some ideas on how to integrate).
