I found that my biggest mistake isn't the direction, but my hands are too quick: when spot prices rise, I want to add more; when there's a pullback, I rush to exit; futures are even more ridiculous, my brain thinks I can hold on, but my account already concedes for me. To put it plainly, position sizing is one thing: first assume you'll make the wrong judgment, then leave room for "still alive after making a mistake," don't treat emotions as fuel.

Recently, I've been hearing a lot of criticism about the stacking of yields from pledge and shared security strategies being called "layered dolls," and I resonate with that: it sounds very attractive, but layer after layer, you think you're stacking returns, but you're actually stacking fragility. Anyway, I’m forcing myself to do one small thing now: first, decide where to take profit, don’t wait until my heart races to start making excuses. That’s it for now.
