Two people with the same level of skill and capabilities work in the same office. Let’s call them Bill and Nick. Both arrive at 9:00am and leave at 5:00pm.
Bill works without taking the slightest breather. He does various tasks at the same time and runs from meeting to meeting all day, as well as eats lunch at his desk. Sound familiar?
On the contrary, Nick works intensely for 90 minutes without stopping, then takes a 15 minute break before starting up again. At 12:15 he leaves for a 45 minute lunch and goes to a gym nearby. At 3:00pm he closes his eyes at his desk for a little nap, sometimes sleeping 15-20 minutes. Lastly, around 4:30pm he leaves the office for a 15 minute walk.
