Today’s Mental Detox corrected a belief many high-achieving women carry: Multitasking is not productivity. It’s fragmentation. We learned that the brain does not multitask—it switches. And every switch comes with a cost: reduced clarity, lower decision quality, and accelerated mental fatigue. We looked at why leaders like Elon Musk intentionally eliminate switching, breaking their days into focused blocks so they can finish one cognitive lane before entering the next. This isn’t control—it’s protection of attention. Declaration: I do not switch lanes without purpose. I honor my attention. I complete. I build.
