I pride myself on multitasking but analyze: can I actually multitask? Map tasks I think I'm multitasking: are any actually parallel or am I just switching fast? Calculate: if multitasking is really rapid task-switching with 40% efficiency loss, what's it costing? Show me the multitasking reality: I can't actually multitask, I'm just switching badly. Give me the single-focus commitment: one task at a time, actually finish it. Include: whether my "multitasking" is just scattered focus, what it's costing in quality and time, and how to force sequential work.
