Dr. Sahar Yousef, a cognitive neuroscientist who studies productivity and brain performance, argues that people work best when they align their habits with how the brain and body function. Her central message: multitasking is a myth, attention is limited, and productivity starts by removing distractions—not by squeezing more into the day.

Why attention matters

• The brain works best by focusing on one task at a time. Switching between tasks creates a switch cost: it takes time and energy to reorient.
• A demonstration in the interview showed that alternating between writing letters and numbers took much longer than completing each sequence separately.
• Task-switching also creates attentional residue: thoughts from the previous task linger and interfere with the next one.
• Attention supports memory and learning. If you do not attend to something, you are unlikely to remember it.
• Notifications, open inboxes, meetings, and visible devices make sustained focus harder. The interview cites research suggesting knowledge workers may spend an average of over two hours a day bouncing between screens and tasks.

Start with the foundations

1. Protect sleep. Aim for at least seven hours a night. Too little sleep can impair thinking and emotional regulation.
2. Improve your relationship with technology. App and device defaults often encourage engagement, not your productivity.
3. Reduce interruptions. Turn off nonessential notifications and set up “VIP” exceptions for genuinely urgent people or messages.
4. Add friction to distracting habits. Put your phone out of sight or in a designated place during focused work; consider a lockbox if helpful.
5. Choose long-form content more often. Short-form content can encourage rapid, shallow consumption. Make time for sustained reading, films, learning, and in-person connection.

Make technology less compelling

Yousef compares digital platforms to highly processed food: they increase stimulation, make use effortless, and fail to satisfy deeper needs.

• Use grayscale: Her lab’s study found that participants spent about an hour less on their phones per day after using grayscale for three weeks.
• Limit infinite scrolling: Set clear stopping points and curate what you consume.
• Meet needs directly: Social media may imitate connection, but real conversations and time with other people better address the need for belonging.
• Notice how you feel afterward: Consider whether an activity leaves you satisfied or regretful, rather than judging it only by how enjoyable it feels in the moment.

The five-step focus sprint

A focus sprint is a structured period of concentrated work. Yousef says her research found this approach can help people do up to twice as much work while making fewer mistakes.

1. Schedule it in advance. Block the time on your calendar so you—and your team—know you are focusing.
2. Choose a clear output. Define what you will produce, rather than vaguely saying you will “work on” something.
3. Break it into small actions. Write a concrete execution list so you do not have to decide what to do next mid-sprint.
4. Remove distractions. Put away your phone, silence notifications, and use headphones or music only if they help you concentrate.
5. Set a timer. A visible countdown can create urgency and help work stay within the allotted time.

Prioritize meaningful work

• Identify your MITs—your one to three most important tasks for the day. Ask: “What would my future self thank me for?”
• Use short gaps for LITs—small, lower-priority tasks—rather than letting them displace meaningful work.
• If you cannot tell what matters most, clarify your longer-term direction. Yousef calls this your “Everest”: the destination you are trying to reach.
• Break big goals into manageable steps. Focus on daily progress—“pedals over podiums”—instead of fixating on the distant outcome.

Work with your natural energy

People have different biological rhythms, or chronotypes. Some naturally function best early, some later, and many have a dip followed by a second peak. Schedule demanding focus work when your attention and energy are strongest, where circumstances allow.

Take real breaks and support creativity

• A good break gives your brain a pause from processing information. Scrolling or reading may keep it working.
• The interview describes a study in which breaks involving nature were most restorative, followed by doing nothing; scrolling was least restorative.
• Try a walk, fresh air, natural light, or a simple hands-on activity. For a quick break, doing something with your hands can make it harder to reach for your phone.
• For creative problem-solving, first immerse yourself in the problem, then step away. A different activity or environment may help ideas connect in new ways.

Redirect unhelpful thought patterns

Yousef advises recognizing rumination and then redirecting attention rather than repeatedly reinforcing the same loop. The brain changes with repeated use, so the thoughts and behaviors we continually reinforce can become more established. For persistent or distressing mental health concerns, seek appropriate professional support.

Main takeaway

Be intentional with your time and attention. Protect sleep, reduce digital noise, focus on one task at a time, and break important goals into practical steps. The aim is not merely to do more, but to make room for work and relationships that matter.
