Locked In

What if your greatest career advantage isn't working harder or answering faster, but learning to concentrate deeply in a world engineered to distract you? In an age of endless notifications, exploding meeting loads, and constant chat pings, the ability to focus has become the scarcest and most valuable skill in knowledge work. Locked In reveals why responsiveness feels productive but rarely produces your best thinking, and why the people who protect their attention gain a lasting, compounding edge. Drawing on cutting-edge neuroscience and research from Gloria Mark, Mihaly Csikszentmihalyi, Anders Ericsson, and others, Brennan Renvik translates hard science into a practical system anyone can use, whatever their job or schedule. Inside, you'll discover: - Why concentration is the new currency and how shallow work quietly sabotages your best output - The neuroscience of deep focus, flow, and the restorative power of genuine rest - How to run a brutally honest time audit and design a workspace that refuses interruption - Four proven models for structuring deep sessions, from daily rhythms to full retreats - How to renegotiate email and chat, manage a busyness-obsessed boss, and reclaim your evenings - A concrete ninety-day concentration practice to rebuild your attention for good Stop being merely busy and start doing the work that actually matters.
