Organizing the data; seeing it in the context of a bigger picture. After spending several years taking notes on a number of topics that I thought had value and wanted to share in thoughtful and coherent way, it turned out to not be as simple as just drafting an outline. The connections between topics weren't clear in a satisfying way. I spent a lot of time thinking about it developing a number of outlines that didn't quite work. Then I found a book about learning and the method that author used to develop his book, using a 'memory map'. Julie has talked about it. In any case, once completed the memory map allowed me to visualize information from a number of notebooks I had on a number of subjects, in a relatively short time. When I looked at the final memory map, which was a number of sheets of paper taped together on the floor, a few months of struggle came together almost instantly. For anybody struggling with information overload, I highly recommend this technique.
