It& #39;s a terrible mistake to think you have to have an opinion on everything. You only have to have an opinion on a few things. 

认为自己应该对所有事情有看法是一个非常可怕的错误想法，你只需要对几件事有态度就够了。 

In fact, I& #39;ve told students if when they got out of school, they got a punch card with 20 punches on it, and that& #39;s all the investment decisions they got to make in their entire life. They would get very rich because they would think very hard about each one. And you don’t need 20 right decisions to get very rich, you know four or five will probably do it over time.

事实上，我跟学生说过，假如他们离开学校，得到一张打孔卡，上面只可以打20个孔，这就是他们一生要做出的投资决定，他们会变得非常富有。因为他们会认真对待每次决策，而且变富有不需要20次全部选对，只要选对4-5次就可以实现了。

I don& #39;t worry too much about the things I don& #39;t understand. If you understand some of these businesses that are coming along and can spot things on, If you can spot an Amazon, for example, I mean it& #39;s a tremendous accomplishment that Jeff Bezos done and I tip my hat to him, he& #39;s a good guy too. But could I have anticipated that he would be the success and 10 others wouldn& #39;t be? I& #39;m not good enough to do that.

我不担心我不懂的事情。如果你了解某些正在兴起的企业并且能发生某些机会，比如你能发现亚马逊的潜力，这是杰夫·贝佐斯一项非常了不起的事业，我向他致敬。杰夫是一个非常出色的商人，也是一个非常好的人，但问题是我怎么才能预料到他可以成功但其他10个人不会呢？我觉得我做不到。

Fortunately, I don& #39;t have to form an opinion on Amazon and I do form an opinion on the Bank of America, and I form an opinion on Coca Cola. Coca Cola has been around since 1886, there& #39;s 1.8 billion 8 ounce servings of Coca Cola products sold every day. Those are the kind of decisions I like to make. You may have an entirely different field of expertise than I would have and probably much more up the day than terms of the kind of businesses that we& #39;re seeing about. And you can get very rich if you just understand a few of them and understand their future.

幸运的是，我不是必须要去判断亚马逊的好坏，但我对美国银行、可口可乐有判断。可口可乐从1886年就成立了，每天会有18亿瓶8盎司的可口可乐卖出去，这些是我乐于去决策的。您可能拥有与我完全不同的专业领域，可能比我了解更多详细的，我所看不到的最新情况。同样，如果你了解这行的某些企业，并且能够预测他们未来的某些情况，你也可以变得很富有。
