Concentration rather than Multi-tasking.

Concentration -- why bother?

Concentration is worth building because it is a foundational skill; it supports almost everything else one might do. In that way it's like intelligence. In fact, definitions of intelligence often include concentration as a component. Anecdotes about famous achievers of history suggest that one thing they shared was a phenomenal ability to get fully immersed in … something.
Michelangelo spent two years on his back, two feet from the ceiling, painting the Sistine Chapel. I myself would have spent most of that time idly wondering whether to have pizza that night or soup.
In fact, according to the stories, only the pope could break the great artist's concentration. He kept coming in to ask, "How's it going?" Finally Michelangelo "accidentally" dropped a hammer that landed too close for comfort, and the pope stayed away after that.

The proof
In one experiment, people were taught certain basic meditation techniques and then asked to meditate while hooked up to machines that scanned what their brains were doing. In people who attained a deep, meditative state, it turned out, the area of the brain known to be associated with attention became active while other areas -- those associated with emotion, for example, or with processing external stimuli -- went dormant.

Researchers then hooked brain-scanning equipment to two groups of test subjects: seasoned meditators with thousands of hours of experience and novices. With each group, when the meditators seemed to be fully immersed, the researchers set off various distractions nearby -- a blaring TV, a crying baby, a gunshot, stuff like that.

In the novices, each event triggered brain waves that spread to other parts of their brains and did not die away for a long time. In the experienced meditators, each event set off a brief burst of brain activity in one limited area and then the brain went back to its former state: In short, the input was noticed, registered and set aside.

That looks like dead-bang proof that meditation enhances a person's underlying ability to concentrate. Of course it's also true that meditation classically aims to detach meditators from the world and get them concentrating essentially on nothing. I, personally, would rather concentrate on something. I don't want to detach from the world, I want to stay in it and get something done. I don't know of any definitive proof that the power of concentration developed by meditation can be applied, for example, to flying a plane through a thunderstorm.

But the broader point seems indisputable: Concentration is a skill. If it isn't used, it can atrophy; if it isn't trained, it fails to develop past a certain point. But by the same token, with the proper training and practice, it can be developed to a level of fearsome intensity.

Preferably, this begins in childhood (which is where parents and other elders come in) but it's never too late. Adults with normal powers of concentration can strengthen those powers with simple exercises such as the following:

• Count backward from 100 slowly and steadily.

• Count backward from 100 by threes.

• Simply look at an object for a set period -- say, 15 minutes.

• Building on the previous exercise, remove the object and picture it for that same period.

And if the buzz of distracting thoughts grows intolerable, stop what you're doing, make a list of everything on your mind at that moment, choose one thing to focus on, and then schedule a time to deal with all the rest. Giving your anxieties appointments, I find, tends to make them stop petitioning for attention now.
In short, I stand with those Zen masters who, when asked how they achieved enlightenment, answered, "When I walk, I just walk. When I eat, I just eat."
