Deep work block: what it is and what it means

The deep work block is a non-negotiable, protected time slot dedicated to work that requires sustained concentration, analytical or strategic thinking, or the production of complex content. It belongs in the early morning hours, when cognitive performance is generally at its peak. The effective duration falls between 90 and 180 minutes: beyond this limit, the quality of thinking declines regardless of intention.
