我作为量化分析师生涯中最重要的教训是：模型并非现实。

市场保持非理性的时间可能比你保持偿付能力的时间更长。

Now, I am not going to stand here and tell you that failure is fun. That period of my life was a dark one, and I had no idea that there was going to be what the press has since represented as a kind of fairy tale resolution. I had no idea then how far the tunnel extended, and for a long time, any light at the end of it was a hope rather than a reality.

When you need to innovate, you need collaboration.
