Focus , a crucial ability - Christina Bengtsson

What is Focus?

First things first. What is focus, really? Experts define focus as the act of concentrating your interest or activity on something. That's a somewhat boring definition, but there is an important insight hiding inside that definition.

In order to concentrate on one thing you must, by default, ignore many other things.
Here's a better way to put it:
Focus can only occur when we have said yes to one option and no to all other options. In other words, elimination is a prerequisite for focus. As Tim Ferriss says, “What you don’t do determines what you can do.”

Of course, focus doesn't require a permanent no, but it does require a present no. You always have the option to do something else later, but in the present moment focus requires that you only do one thing. Focus is the key to productivity because saying no to every other option unlocks your ability to accomplish the one thing that is left.



The Myth of Multitasking

Technically, 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.

What is impossible, however, is concentrating on two tasks at once. You're either listening to the TV and the overflowing pot of pasta is background noise, or you're tending to the pot of pasta and the TV is background noise. During any single instant, you are concentrating on one or the other.

Multitasking forces your brain to switch your focus back and forth very quickly from one task to another. This wouldn't be a big deal if the human brain could transition seamlessly from one job to the next, but it can't.

Have you ever been in the middle of writing an email when someone interrupts you? When the conversation is over and you get back to the message, it takes you a few minutes to get your bearings, remember what you were writing, and get back on track. Something similar happens when you multitask. 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.

Switching cost is the disruption in performance that we experience when we switch our focus from one area to another. One study, published in the International Journal of Information Management in 2003, found that the typical person checks email once every five minutes and that, on average, it takes 64 seconds to resume the previous task after checking your email.

In other words, because of email alone, we typically waste one out of every six minutes.
