Letting your mind “wander” in this fashion is extremely useful from a brainstorming” point of view and the creation and use of mind maps has been shown to be useful in study, problem solving and decision making processes.
Free downloadable Mind Mapping Software includes a program called FreeMind. As the name implies this is a free application and one that is extremely user friendly and intuitive.
FreeMind is a premier free mind-mapping software written in Java. The recent development has hopefully turned it into high productivity tool. We are proud that the operation and navigation of FreeMind is faster than that of MindManager because of one-click "fold / unfold" and "follow link" operations.
So you want to write a completely new metaphysics? Why don't you use FreeMind? You have a tool at hand that remarkably resembles the tray slips of Robert Pirsig, described in his sequel to Zen and the Art of Motorcycle Maintenance called Lila. Do you want to refactor your essays in a similar way you would refactor software? Or do you want to keep personal knowledge base, which is easy to manage? Why don't you try FreeMind? Do you want to prioritize, know where you are, where you've been and where you are heading, as Stephen Covey would advise you? Have you tried FreeMind to keep track of all the things that are needed for that?
If your company restricts access to downloadable applications, I would suggest you try a program called bubbl.us – available for use and access online, it is not as pretty as FreeMind, however the fact that you can access it anywhere you can access the Internet is a plus in itself. Currently in beta it is also a free program. You can access it here.
