Trend-following is not such a good model. It’s simply eroded. Things change and being able to adjust is what made Mr. Simons so successful. “Statistic predictor signals erode over the next several years； it can be five years or 10 years.

科学应当为人类服务，而不是反过来。

世界是一个舞台，我们只是演员。

饱食终日，宴乐无度，不就是白白地浪费了一天！轻举妄动、胡言乱语、不讲道理、放纵私欲，岂不是就是罪恶的一日！

The true measure of our success will be what we leave for future generations.

我不害怕变老。我更有经验，更聪明，更有耐心。
