Mastery requires focus and consistency.we are capable of doing two things at the same time. It is possible, for example, to watch TV while cooking dinner or to answer an email while talking on the phone.
The human brain cannot perform two tasks that require high-level brain function at once. Low-level functions like breathing and pumping blood aren’t considered in multitasking, only tasks you have to “think” about. What actually happens when you think you are multitasking is that you are rapidly switching between tasks.What is impossible, however, is concentrating on two tasks at once. Multitasking forces your brain to switch back and forth very quickly from one task to another.So when you think you are multitasking you are actually switching your goals.This wouldn’t be a big deal if the human brain could transition seamlessly from one job to the next, but it can’t. Multitasking forces you to pay a mental price each time you interrupt one task and jump to another. In psychology terms, this mental price is called the switching cost.
The power of choosing one priority is that it naturally guides your behavior by forcing you to organize your life around that responsibility.When the brain tries to do two things at once, it divides and conquers, dedicating one-half of our gray matter to each task.The work also reveals that the brain can’t effectively handle more than two complex, related activities at once.
So start focusing one thing at a time if you want your best performance in each work.multitasking is originally a computer term which is only for the computer not for the human brain.
