We wear "multitasking" like a badge of honor. We feel busy. We feel productive. But the data says we are failing.
The High Cost of Switching
Neuroscience tells us that the brain cannot focus on two things at once. When you switch tasks, you leave "attention residue" behind. You are operating at 60% capacity on both tasks.
Single-tasking is a superpower. Do one thing. Finish it. Move to the next. True time management isn't about doing more things at once; it's about doing the right things, one at a time.
