About a month ago, I learned about ResultManager, an add-on program that provides powerful capabilities to MindManager for organizing, visualizing, and tracking these commitments. ResultManager automates the process of using MindManager maps for GTD, allowing me to focus on the work itself and not the management of the data itself. That's important. I have, from time to time, become so caught up in the "how" of GTD to really reap all of the benefits of actually "doing" GTD. Read any online group list or discussion forum and you'll find a number of folks wrestling with that particular question of focus.
The team at Gyronix, led by Nik Tipler and Nick Duffill, have created a tool that helps keep that focus where it belongs - on what needs to get done. It's an astonishing accomplishment; one that, over time, reveals layers of nuance and power that is not immediately apparent. And, like just about every complex and rich application I've adopted, there is a decided learning curve that needs to be mastered to take maximum advantage of that complexity, richness, and power.
