Single-task hour

Multitasking is a tax you pay all day in tiny switching costs. For one hour, refuse to pay it. **How to do it** - Choose the single thing that matters most this hour. - Phone in another room, one tab, one document — no switching. - Log it when the hour is up. **Why it works** The brain is poor at parallel work and superb at sustained attention. One honest hour of single-tasking routinely out-produces a whole fragmented morning.
