The myth of multitasking's prestige

In this article, renowned neurologist Richard Cytowic seeks to expose multitasking as a fool’s errand. Cytowic explains how the brain, like a computer, switches between tasks rather than handling multiple tasks at once.

Instead, he suggests, try to focus on completing one thing at a time.
