What the experts have discovered is that multitasking is actually “task-shifting.” The fact is that you can only do one thing at a time. If you stop doing one task to turn to another task, you must shift all of your attention and energy to the new task. When you turn back to the previous task, you are simply making a shift of attention, like pointing a light beam from one target to another. Then, you must bring yourself up to speed on the old task before you get started again.
