If you’ve never done mind-mapping, I’ve included links below to a few quick guides. I have mind-mapping software (Simple Mind) but I prefer using pen and paper. My technique is a simple one: I begin with a central idea, which I circle, and then (like spokes on a wheel) begin free associating outwards from the central hub. In my example from yesterday’s mind-map, Fort Robinson was at the hub of my mind-map, from which I added other ideas/observations (black butterfly, wind, elms, cottonwoods, officer’s row, bluffs, sky,etc).
Rico Cluster (which is about as close to what I do as possible)
If you’re open to having your mind-map posted here, send it over to email@example.com and I’ll post it, along with whatever comments you want to make. I encourage you to come up with an idea for a flash non-fiction piece, then start mind-mapping it. Can’t wait to see what you create!
