The practical idea
A useful technology plan can include time without technology. The aim is to make deliberate choices about attention, not to maximize a household productivity metric.
Choose one protected activity
Pick a meal, walk, game or project where everyone agrees to put devices aside. Keep the plan realistic and make room for necessary communication.
Give tools a bounded job
If a tool helps organize the activity, use it for that specific task and then put it away. Check the plan against the people, time and resources actually available.
Review what worked
Ask whether the activity felt better, what was difficult and what to change next time. Rest and enjoyment are valid outcomes. There is no need to attach a forecast about the economy to this choice.
