It’s here that we find the primary argument for why doing fewer things is as important for modern knowledge workers as it was for Jane Austen. It’s not just because overload is exhausting and unsustainable and a miserable way to exist—though it certainly is—but because doing fewer things makes us better at our jobs; not only psychologically, but also economically and creatively. Focusing intensely on a small number of tasks, waiting to finish each before bringing on something new, is objectively a much better way to use our brains to produce valuable output.
