Try to get four hours of concentrated work into a workday, and never more than six

Our brain can only work well for a limited time. Research shows that people can usually only think well for a few hours a day. Most people cannot do difficult thinking work for more than 4 hours a day without making mistakes. By working shorter but more concentrated, we can get more done without becoming too tired.

We often think we need to work 8 hours a day. But this is not always feasible for work that requires a lot of thinking. While it is possible to work many hours on simple tasks, “real” work is mentally demanding. People sometimes feel guilty if they don’t work 8 hours. But this may not fit how our brain works. It’s better to look at what you accomplish rather than how many hours you work. By working well for 4 hours, and maybe 6 hours on good days, you can achieve a lot and stay healthy.

It helps to start working early and take smart breaks. Start the day off right and keep breaks short. Pay close attention to yourself: if you notice you’re working less effectively, it’s time for a break. By consciously choosing shorter working hours, you can get more done and feel better.
