I've developed a practice of doodling through meetings that I attend. I've found that it helps me stay engaged with the content, especially when these meetings are at least several hours long, if not most of the day.
Here are a few recent ones that I've done. This one is from the Living Water Association's annual gathering (on Zoom, of course):
And these two are from a recent 2-day event for UCC national staff (also on Zoom):
The idea is that everything I draw relates to something that was mentioned or discussed during the meeting. It helps me listen more closely and note key concepts and ideas.
I recently discovered that doodling meetings can be considered a form of mind-mapping:
The first thing I always draw are the large words at the center of the page. Sometimes they're the first idea that I latch onto, but usually they represent the meeting that I'm attending. Then I fill in the rest of the pages with other pictures, words, and phrases as I hear them. I don't know where they'll go on the page until I put my pen to paper.
I hadn't considered these to be diagrams the way mind maps are considered such, but the concept of mind-mapping has shown me that this is really what I'm doing: converting information into a form that the mind will remember better via images and keywords.
Author and creator Austin Kleon puts it another way: "It’s like emptying out the junk in your brain." Yep, that works, too.
