I almost got thrown off by the market just now. Turning off the price alert is what helped me calm down.

Honestly, floating losses and floating gains aren’t the same thing at all. When the screen is in the green, my mind keeps flipping back and forth about “should I cut?” When I’m up, I’m not in a rush to run yet—I can still think about “should I add more?” Munger put it plainly: loss aversion— the pain of losing one unit has to be offset by making two to make it feel like it’s been recovered.
Earlier that chain upgrade, everyone in the group was speculating whether the ecosystem would migrate. I spent a long time digging through the contract permissions and the rollback/callback mechanism, and didn’t find any obvious traps, but my attention was completely consumed by the thought of “what if someone tries to slip in an insertion during the volatility.”
Anyway, this is how I handle it: when I’m at a floating loss, first check whether the original logic is still intact—no matter what the market’s doing. Shut the interface, and go sleep. Let’s see who can outlast whom.
Holding on to the logic—that’s what really matters. As for mindset, in plain terms, it’s just don’t write extra drama for yourself.
