How I Map Random but Connected Ideas

Well, there is no doubt I am a visual thinker. I use Indesign as a cognitive mapping tool to arrange random thoughts and ideas. I have been writing approx 600 words a day since March 1st, and then going back and tagging ideas. I then use those tags to create cognitive maps of my thoughts. These may be disconnected and unorganized, but they start to form a picture and slowly but slowly I can start to see some threads that will become the beginnings of a project. This is the map as it stands, but it will definitely change, grow and be altered. Indesign is not a great tool for this, but I haven't found anything else that allows me to represent my ideas this way, so there yo have it. (PS. I like arrows.)
