Wroclove.rb 2018 lightning talk proposing an 'offline sandwich' / 'immersion-driven workflow' to contain (not eliminate) distractions. Structure: repeat ~4 rounds per day of (1) offline focus phase 60–90 min (Slack off, phone off, boss can't reach you — deep work / investigation), (2) online phase ~30 min (catch up with colleagues, write to them), (3) off-topic phase (Twitter, coffee). Cites claim that distractions make you dumber than being stoned. Tips: plan the offline phase up front, aim to ship something concrete (commit, write-up, investigation result) for instant gratification instead of just quitting when time ends. Works best with remote work, even better with asynchronous work, best with remote+async+autonomy — suggests convincing your boss.
