It may sound a little cold, but marriage is a project, just like everything else on your to-do list. So why not use Getting Things Done as Marriage Counseling? I actually use some Getting Things Done (aff.) techniques with my marriage, notably having reminders and to-do items related to being a good husband – remembering birthdays and anniversaries, setting goals for our marriage, remembering to do household chores etc.
