I too am an attorney. While the client list is huge, the list of open cases at anyone time is like anyone that has an active practice. All of my open cases are projects. The project is headed Smith, John Estate Plan, Next action: Smith John send engagement letter.(That way when the full to do is shown each next action is directly under the Project) When the engagement letter is sent the next action is waiting for etc.. Each client Matter is a project. When its closed the project is closed. I distinquish the Client Matters(Projects) from the client list. When I have a project that involves notifications etc the project might be" Notify all Elder Law Clients of changes in medicaid Law"
Thats a project. I then go to my client list that I keep on a case management system and get the list.
I use the palm simply as a list manager and an easy way to see at a glance where everything is. I go to a case manager system and the case files for everydetail beyond that.
I have said before on the list that my variation from strict GTD is at the weekly review I pick the things that are important that require concentrated time.... drafts, accountings, involved planning letters etc and make an appointment during the week for that specific item. I try and schedule time at least 4 times a week that is an uninterrupted appt. with myself to get the work done. The rest of the week I can devote to appts, calls, and emergencies and general work. By commiting to work on a few key projects that require concentration every week at a designated time I accomplish far more at the end of the month that when I dont do that.
