说起来有一件很奇怪的事情。

There's a strange thing to say.

人们总说不要沉浸在自己的世界中，因为这会隔绝你和他人的交流。但当你想做成某事的时候，沉浸于自己的世界反而是最高效的，这到底是为什么呢？

People always say don't get caught up in your own world, because it cuts you off from other people. But when you want to do something, it's most efficient to immerse yourself in your own world, why is that?

我认为，人和人之间需要交流，提升自我也少不了沟通。当你想获得什么的时候，或是一块饼干，或是一辆车，都需要你通过和他人交流的方式去争取，所以当你用一面墙隔绝自己和这个世界是不可行的。

I believe that communication between people is also indispensable for self-improvement. When you want something, whether it's a cookie or a car, you need to fight for it by communicating with others, so it's not feasible to separate yourself from the world with a wall.

但如果你有了一个清晰的目标，而这个目标非常难以实现，以至于你要投入大量的时间和精力。这种时候，还是自成一个小世界，隔绝外界的各种干扰因素，才能更高效的达到你所期望的目标，这或许被称之为“专注”。当你处于这种专注的状态，或许会遗忘某些事物，但是你的情绪和成功率会很高。有时候，你甚至会惊讶于自己的好状态。

But if you have a clear goal, and that goal is so difficult to achieve that you have to invest a lot of time and energy. At this time, it is better to form a small world of its own, isolating various distractions from the outside world, in order to achieve your desired goals more efficiently, which may be called "focus". When you are in this state of concentration, you may forget something, but your mood and success rate will be high. Sometimes, you may even be amazed at how good you are.

那么，熟练掌握自己世界的切换是最优的选择吗？

So, is it best to master the switch between your own worlds?

人无法完全隔绝这个世界，就算想要达到“沉浸”的状态也会有各种烦扰，突如其来的消息，预料不及的工作。一旦状态被打断，或许就很难再次进入这种状态了。同理，当你处于一种兴奋的状态，迫不及待的倾诉，往往也做不到一瞬间屏蔽外界干扰。

People can't completely isolate themselves from the world, and even if they want to achieve a state of "immersion", there will be all kinds of troubles, sudden news, and unexpected work. Once the state is interrupted, it may be difficult to get into it again. In the same way, when you are in a state of excitement and can't wait to talk, you often can't block out external interference for a moment.

那么，在什么时候切换是最好的呢？

So, when is the best time to switch?

我认为，外部因素是干扰人的状态的绝大部分原因。很多时候，你只是吃饱了，睡早了，装扮精神了，有合适的工作环境了，你的做事效率就能提高很多。甚至小到你买了一件新衣服，吃了一颗糖，受到一句夸奖这种琐碎的事情。内部因素可能就在于你的心态，对自己有信心，相信这件事非我不可，烦躁的时候大哭一场，开心的时候记录一下，每每回想，你就会平静许多。

In my opinion, external factors are the vast majority of what interferes with the human state. Many times, you just eat enough, go to bed early, dress up, and have a suitable working environment, and your work efficiency can be improved a lot. Even as small as buying a new dress, eating a candy, and receiving a compliment. The internal factor may be your state of mind, having faith in yourself, believing that it is necessary for me, crying when you are upset, recording it when you are happy, and every time you think about it, you will be much calmer.

观点总是看起来矛盾，但在这矛盾中寻找平衡点也不失为一种乐事。或许当你有什么想法的时候，你也可以这么做。

Opinions always seem contradictory, but it is also a pleasure to find a balance in the midst of this contradiction. Maybe you can do the same when you have something in mind.
