Qingze wrote in *"The Realm of Clarity"*: "It's impossible to find a perfect trading theory; you must give up the effort to search for an investment holy grail." "Any trading theory can only explain part of the market's movements." "Define your circle of competence and operate within it." This resonates with my own trading insights over the years. Most of the time, I can't make sense of the market trends. But there are certain parts I can read very accurately—like my judgment on bull markets or my ability to spot certain altcoin pump patterns. This is my circle of competence. Within this circle, my understanding is very strong. Trying to make money outside of it is extremely difficult. I realized early on that I'm not suited for playing high-leverage contracts—honestly, most people aren't. Be intentional about recognizing and understanding your circle of competence. Make more money where the fish are, and lose less where there aren't any.
