How effective is "turn" multitasking?

Reading time, there will always be a teacher said to us: to concentrate, the heart of a use! But the reality of experience tells us that people are often exposed to multitasking. Wouldn't it be better if there was a way to get us to multitask and deal with multitasking effectively?

There is always a plausible saying, "Do one thing at a time!" ”

Can a man do more than one task?

I've always wondered why such a simple question would cause so much controversy. What is even more surprising is why so many academics have come to the conclusion that "people cannot multitask"?

Because the fact is obviously: "Every day, we have to do a lot of things at the same time ...".

The strangest thing is that there is a discipline that specializes in how to improve efficiency: "Holistic learning".

(a) at a particular time, the human brain can only deal with one thing.
This is also the obvious fact. Modern computers are equipped with a "multitasking operating system", although a single computer has only one central processing system
, but under the dispatch of the operating system, the computer "seems" to do many things at the same time. Note that it is "looking" rather than "in fact". In fact, the CPU of a computer is like a human brain, in a particular
Moment, can only do one thing.

(b) The switching task itself consumes energy.
This is where I can't disagree with the scholars ' conclusion: switching tasks not only consumes energy, but frequent switching tasks inevitably result in a significant decrease in efficiency.

(c) The reason most people are unable to multitask is because of their "OS lag".
The same computer, with a DOS operating system, can only "single-tasking", because the operating system is a single task. It can be "multitasking" if it's windows, although it's actually "simulating" multitasking.

So, the reason most people can't do several things at the same time is because they lack training.

(iv) design a dispatch system for oneself
The key to the dispatch system is to see "can divide it into several stages" before doing anything.

Another key is to have a sophisticated system of records. The vast majority of people never think they should do a job record, think that it is too much trouble, and ultimately, the reason for inefficiency is here: because there is no record, soon began to omit important items.

(v) Set a time slice interval for yourself
This seems a bit contradictory, in order to be able to multitask, it is necessary to improve the time slice single task "concentration" ability.

For a certain amount of time, do only one thing, for example, 1 hours, 2 hours, or shorter, 30 minutes. Everyone's "concentration" ability is very different, the difference is very big. A lot of people can't do it for 5 minutes. Therefore, the efficiency is very low, and then there is no way to complete any task. So there is no way to multitask.

(vi) Optimization of its own scheduling system
Continue to summarize their behavior patterns, constantly observe their own efficiency, and constantly review the rationality of task segmentation, and constantly improve the efficiency of their records system ... And then constantly optimize their own scheduling system.

Or that sentence: easier.

And the more amazing is that people can only do what they want to do, or it will be dragged and dragged, not to mention what multitasking to deal with.

People work, can be divided into active or passive. What you want to do, will take the initiative to do, what is required to do, on the one hand may be resisted, on the other hand, it is impossible to try. Only what you want to do.
Son, will really do their best. One of the prerequisites for doing this is to "think it through"-if it's something that someone else wants to do, people will usually think more about how to meet the requirements (preferably not many).
Instead of really figuring out "how to do the best".

What one wants to do is broadly divided into two categories, "feasible and infeasible", or "generally feasible or more feasible"--in a word, good or bad. A lot of things that are not feasible for a
Some people, feel is feasible, a lot of general things, for some people, feel is the best ... It's just a feeling, not necessarily a fact. However, many people only believe in their own feelings, even when someone tries to
For him to straighten out all the possibilities in order to weigh them carefully.

The question is: "Follow the Feeling" How much difference does gambling have? For the most part, out of the sense of experience, the difficulty is too great, so, people's life is often only in luck, in other words, the person, the task in the day.

Now there are dual-core, quad-core computers, but in fact, the number of tasks that the computer will handle at the same time is always far more than the number of CPUs ...
