You mention that offloading tasks into a permanent storage medium helps free working memory. In my experience, once I write something down I often forget to revisit it, and that sense of ‘it’s safely written down’ sometimes leads to more procrastination. How can one avoid this issue?

Nice read, you wrote mostly about distractions from the outside environment but what about the distractions created by our brain, once the brain understands that we are trying to programme it it will create distractions from within, old memories, new totally unrelated thoughts keep creeping in from no where how to control them
