I found that the biggest factor affecting sleep isn't the lack of profit, but the paper loss from floating unrealized losses. Even if the numbers aren't large, the brain automatically fills in the gaps with "What if it drops further," then starts repeatedly reviewing, thinking about adding to the position or cutting losses, the more I think, the more restless... Floating gains are actually easier for me to take as "what should have been there all along," which is quite unreasonable.

Assuming I haven't changed my strategy or position, the floating loss is just a matter of probability playing out, but emotions amplify it into "I did something wrong." So recently, I set a simple rule for myself: as long as it's within the plan, look at the market less, and calculate the trading costs (fees + slippage) clearly before acting. Otherwise, if I keep tinkering, the loss might not be in the direction but in the friction.

Lately, everyone compares RWA and US Treasury yields to on-chain yield products, and I also get tempted, but honestly, the steady-looking returns are more likely to get me excited; conversely, when losses appear, I want to "fix" them immediately. Loss aversion really seems to come out at night.
