It is also interesting to think about this alongside Clive Thompson’s exploration of to-do applications. I am intrigued to how they sometimes crossover.
Most significant thinkers, writers, and creators throughout history have kept something resembling a commonplace book. While many may want to attribute the output of historical figures like Erasmus, Newton, Darwin, Leibnitz, Locke, or Emerson to sheer genius (and many often do), I might suggest that their works were the result of sustained work of creating personal commonplace books—somewhat like a portable Google search engine for their day, but honed to their particular interests. (One naturally can’t ignore their other many privileges like wealth, education, and time to do this work, which were also certainly a significant factor in their success.)
