抄一段大师的话

The most interesting thing about forecasting is that it is never accurate. It is always based on today's knowledge, which is almost always wrong when applied to the future.

The unpridictablility of cyclical patterns is the only constant.
Every cycle is different, even when the underlying causes and effects appear the same.
