For most people in most non-entry-level knowledge work jobs, the answer to the question will be somewhere in the 30 to 50 percent range (there’s a psychological distaste surrounding the idea of spending the majority of your time on unskilled tasks, so 50 percent is a natural upper limit, while at the same time most bosses will begin to worry that if this percentage gets too much lower than 30 percent you’ll be reduced to a knowledge work hermit who thinks big thoughts but never responds to e-mails).
