Lately, being temporarily in the red has woken me up in the middle of the night. Clearly, my position isn't large, but I keep replaying in my mind, "If only I hadn't confirmed at that moment."

When I was in profit, I slept quite soundly, probably because the gains still didn't feel like "mine," but losses felt like cash being pulled out of my pocket. Honestly, loss aversion feels so real.

Now I try to suppress myself with a "Mining Lamp Rule": before opening a position, write down the maximum loss I can tolerate, and when I reach it, turn off the lamp and walk away—don't grope in the dark.
The social mining approach is quite similar; attention is fuel. The more you stare, the more anxious you become, and in the end, what you mine out are emotional pits... Anyway, I first turn off the reminders so that temporary losses don't creep into my dreams along the screen.
In the end, I still go back to the Mining Lamp Rule: don't keep the lamp on for too long; people will get dizzy.
