“When you are walking, walk. When you are sitting, sit,” is ancient wisdom. Hopping rapidly from one thing to the next, answering the phone while we’re shuffling papers while we’re sipping a latte, we fritter away our attention and forget more easily. ….. That is why learning to be a unitasker in a multitasking world is so vital. Rather than divide our attention, it is far more effective to take frequent breaks between intervals of sustained, one-pointed attention. Debunking the myth of multitasking, we become much better at what we do and increase the chance of being able to remember the details of work we have done in the past.
