I don’t know anyone thinking more deeply, or more holistically, about the crisis of our collective attention than Johann Hari. This book could not be more vital. Please sit with it, and focus.

Superb . . . Stolen Focus is a beautifully researched and argued exploration of the breakdown of humankind’s ability to pay attention, told with the pace, sparkle, and energy of the best kind of thriller.

Goes deeperDeep Work
Johann Hari says what feels like multitasking is switching back and forth, and each switch costs performance. Cal Newport names the mechanism: attention residue stays stuck on the first task, especially thick when that task was unbounded and low intensity, and people carrying it are likely to perform worse on the next.
Goes deeperFlow
Johann Hari says focus needs a positive goal once distractions go, ideally one that stretches ability without exceeding it. Mihaly Csikszentmihalyi explains why: enjoyment sits where challenge matches skill, between boredom and anxiety, and the challenge must rise as skill grows.
