I am gratified to hear of the success Mark has had with mind mapping. I first learned the technique in 1983 and have been an avid mind mapper ever since. I have taught hundreds of people to mind map and continue to do so to this day.

The key concept of mind mapping is articulated by Edward Tufte in his seminal work about the visual display of information -- don't stack information in time -- display it adjacent in space. The mind map keeps everything in front of you rather than buried in stacks of notes or pages.
