Paranoia walking on the right path, like Lengxi, is our only available investment tool. Although paranoia may not always be right, it is paranoia that ultimately achieves great victory. Therefore, the ultimate excellent investor cannot do without the habit of paranoia, which determines the outcome. Either you stubbornly persist, or you stubbornly refuse to participate in this market. Making investments that swing up and down and strike right and left will definitely not yield outstanding results, which means that the ultimate test of investment is your carrying capacity. For example, if you don't have as much insurance float as Buffett and so many ways to maintain returns, then the last weapon you have is paranoia. We all know a saying: 'Without madness, one cannot survive.' Although paranoia may not always be right, it is paranoia that ultimately achieves great success. Moreover, we must walk on the right path of value investing, which means strictly following objective laws and the law of value, holding the equity of the most growing high-quality enterprises. Paranoia will ultimately lead to great success.
