I've tracked my productivity for two years with time logs, and the biggest myth I've found is that multitasking saves time—it actually adds about 23 minutes to refocus after each switch, per a study I read. Yet I still catch myself juggling three tasks at once when deadlines loom, so I'm not immune to the trap. Is the real problem not a lack of willpower but the way we structure our workdays around constant interruptions? I wonder if most people could reclaim hours by simply batching similar tasks, but I haven't tested that enough to be sure.
