Why You Can't Focus Anymore (Your Attention Is Fragmented)

Leo has been "working" for three hours. Coffee gone cold. Finished: nothing. It's not laziness — it's physics. Every time you switch tasks, part of your mind stays behind. Psychologists call it attention residue. And every switch charges a hidden tax on top of it. In this video, we follow Leo through the science of fragmented attention: Sophie Leroy's experiments on the residue that haunts every unfinished task, the research showing all that switching can eat up to forty percent of your productive time, why Stanford's heaviest multitaskers turned out to be the worst at multitasking, and the cruel twist — interruptions can make you faster while quietly breaking you. Plus three research-backed moves to fuse your attention back into one thread.
