"The premise of mind-mapping is simple: Start by getting down a big idea or project, and then branch off your idea with complementary ideas or smaller projects that help you attack the big one. Before long you'll have a detailed map with lots of small projects, tasks, and to-dos that can help you make progress towards tackling a big goal.
The beauty of mind-mapping software is how it encourages you to document your train of thought.
If you're a visual learner, or just someone looking for an easier way to brainstorm ideas and quickly set in to work on them, mind-mapping software can help you organize your train of thought into discreet and organized projects and ideas.
If you have a hard time getting notes into task lists and to-dos, mind maps can help you keep your thoughts together and connected so you'll be able to tell at a glance what task or to-do reminded you of another idea or project."
