When one day I lost all my assets in the currency circle, I began to change my past. I really think over and over again every day where I made a mistake in my judgment and where I went wrong. The final summary is the two mentality of greed and unwillingness to admit defeat. However, I believe that recognizing the flaws in one's own human nature is often not enough, because human nature itself is natural and cannot be discarded. So, all I can do is... try to be rational. And my rational judgment was not wrong, at least not that time. I admit that I will make mistakes, and I will make mistakes one day. So when I make investments in the future, I no longer dare to put all my eggs in one basket.
