I set a rule for myself: don't let the outcome of any single trade determine my mood.

Spot trading is hard to hold onto, mostly because of having too large a position—when it rises, I want to add; when it falls, I panic;
Futures are simpler—leverage gets the best of you, and the market shakes a little, and you're wiped out.
Honestly, I now split my positions into small pieces—only the parts I can sleep peacefully with count as my holdings; if I can't sleep, I cut down until I can.
Recently, everyone’s been talking about rate cut expectations, the US dollar index moving with risk assets—I don’t really understand what macro is trying to do…
Anyway, I stick to my rules: keep some stablecoins, take it slow, for now, that’s it.
