There are two kinds of sadness in trading:
First, always trying to use one investment method to solve all problems and explain all phenomena, being self-centered and intolerant of other people and methods;
Second, always trying to find a perfect investment method, not realizing the inevitability of gains and losses, so looking around and worrying about gains and losses.
The first type of people become paranoid, criticizing the market as soon as they are not satisfied, and regard themselves as the truth. The second type of people become fence-sitters and can never be firm once.
The realm of investment is the natural result of long-term learning and practice, not a magical and mysterious thing. Don't make the originally complex too simple, and don't make the originally simple too complicated. This is not only a reflection of a person's investment savvy, but also a lifelong self-cultivation in the investment industry.
