@jellydiver I always carry a paper notebook, for ad hoc thoughts (and sketches + doodles). I otherwise use Evernote a lot, detailing each step in research and dev projects... and also a 'plus24' journal where I detail some of the good things from each day. Otherwise pseudo photo journaling - I spend the time to curate the photos we take, and make 'reflecting on the weekend' collages each Monday morning.
