I multitask to save time but analyze: am I actually slower? Map multitasking: tasks attempted simultaneously, quality of each, time to complete. Calculate: multitasking time vs. sequential time vs. task-switching cost. Show me the multitasking myth: humans can't multitask, only task-switch badly. Give me the truth: multitasking is making me slower and worse. Include: whether multitasking is costing time, what task-switching penalty is, and how single-tasking would speed me up.
