Just downloaded the 2021 GTD PDF Organizer. A 30-second glance makes me think I can work easily online in the editable PDF. And probably print out select pages at will. Would be interested in hearing of the experiences of others with this tool.
Got as far as appointments yesterday. The Actions/Info column next to Appointments really adds a dimension and depth to the idea of both project management and next actions. I immediately identified next actions and acted on them for my two appointments for today. I guess I am saying that this workbook moves GTD from theory to implementation, and I really like "seeing it in 3D".
