2010年4月,雷军创办小米,2011年8月16日小米I代惊艳亮相,一年之后,历经重重困难的小米才勉强站稳脚跟。2013年,小米开始步入发展快车道。此时,雷军提出了“飞猪理论”,即站在台风口,猪也能飞起来。“飞猪理论”的本质并不复杂,概括起来就四个字:顺势而为。

    伴随着“飞猪理论”的迅速走红,争议也由此而来,不少大佬矛头直指“飞猪理论”。如马云认为,“猪碰上风也会飞,但是风过去摔死的还是猪,因为你还是猪。”百度李彦宏在出席IT领袖峰会时也对“飞猪理论”表示不满,他认为其充满投机思维。

面对外界的质疑,雷军不得不对“飞猪理论”做出更全面的解释,反复提及“1万小时定律”和“选择比努力重要”两大理论,前者是“飞猪理论”的前提,没有深厚积累即便遇到发展良机,也会失之交臂;后者是“飞猪理论”的核心,“不能只顾埋头苦干,不去抬头看路。应该花足够时间研究风向,研究风口,这样你成功的概率要大很多。”

    中国经济正处于新旧动能的转换期,传统的经济业态正转型升级,“互联网+”等这些站在“风口”的新的经济业态也层出不穷。新业态的健康发展离不开政府的必要放权、引导支持和监督管理。正如***所说,要深化简政放权、放管结合、优化服务改革,把“放、管、服”有机结合起来。

    Making a public speech is the thing that most people don't want to do. The reason is that we are all afraid of making mistakes in front of others. The more important the speech is, the more frightened we will be. But forget it now. Public speaking is easy. It's just a simple talking, Although I'm a shy man, I've been making speeches and talking on radio and television for more than 30 years. Anybody who can talk can speak in public. Here are some of the lessons I have learned:

    Keep your speech simple. Your audience can't take all of your main ideas, and they can only remember one or two of them, not ten or twenty. So you should prepare one or two of your main ideas very well. But if you can't express what you want to say, then your speech will not be paid attention to. And if you don't have a clear idea of what you want to say, your audience won't, either.

    Organize your speech well. No matter how long or short your speech is, you have to organize your speech—how you are going to open or begin, what main points you want to make and how you're going to close or end. A strong close is usually very important and critical(关键的): the last thing you say is what your audience will most likely remember. If not, they will be confused.

    Keep your speech not long. The standard (标准的) length of a speech is usually 12 minutes. Most people can't put their minds in one thing for too long time, which will make them tired and lose their interest. If you pay no attention to your audience's reaction(反应),the audience will get bored. Of course, your speech will fail.

    Following these suggestions above, you can make a good speech in public, and you will be an excellent speaker, I think.
