Your point about focusing too much on the tools when going digital is important. Often I get sucked into some fancy ToDo app for my short lists of personal tasks. Down I go into the rabbit hole of productivity apps and soon enough I realize I should have just scribbled it on a piece of paper and be done with it instead of buying into a whole ecosystem of digital tools to manage tasks that will be thought of, recorded and completed in minutes or hours.
