About Focus

The focus on the day decreases with the passage of time and needs to be recharged periodically.

In 90 minutes, our brains go from highly focused to inattentive. That's why we end up messing around with the cell phone or surfing.

When famous psychologist K. Anders Ericsson studied people at the top of their fields, such as famous guitarists, athletes, and chess players, he discovered that these people also practiced in blocks of 90 minutes or less, with small pauses between blocks.
