投资的四个维度是回报、风险、成本和时间。令人惊讶的是，绝大多数投资者只关注第一个维度。

The four dimensions of investing are return, risk, cost, and time. Remarkably, the vast majority of investors focus only on the first one.

我是一个糟糕的交易员——总是在趋势确认之前进场。但我是一个好投资人——因为砍仓够快。

I'm a lousy trader because I enter before trend confirmation, but a good investor because I cut losses immediately.

下跌不是风险，不了解才是风险。

A decline is not risk; not understanding is risk.

在过去的几十年里我在完全不懂的行业里赚的钱比在我自认为懂的行业里赚得还要多——因为不懂的时候我会更谨慎。

Over the decades I've made more money in industries I knew nothing about than in ones I thought I understood — because not knowing made me more cautious.
