FreeMind is a premier free mind-mapping
software written in Java. The recent development has hopefully turned
it into high productivity tool. 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?
