Return to the Open Tab
Bring your attention back through one concrete, unfinished action.
Notice which task keeps slipping behind the next notification. Before opening another message, look at what is already in front of you. A sentence may need its final words; a decision may need one missing fact.
Choose a short interval in which that task receives your undivided effort, if your responsibilities allow it. Put distractions somewhere less convenient to reach. Leave a clear note about where to resume if you must stop.
Attention returns through these practical arrangements. Make one of them this morning and give the waiting work a fair chance.
