When it comes to lending and borrowing, I usually consider the liquidation threshold as the "red line." When you're three steps away from the red line, it's better not to force it.

The first step is to draw out your position and collateral ratio (I usually sketch a quick diagram), don't rely on intuition;
The second step is to immediately keep some clean bullets in your wallet—add more if you can, reduce if you need to—prioritize handling the part most likely to be hit first;
The third step is to check your automation setups—authorizations, oracles, limit orders/alerts—don't let a chain hiccup cause you to lose everything.

Recently, the group has been discussing stablecoin regulation, reserve audits, and various "de-pegging" rumors. Honestly, the more you read, the more your emotions can get carried away, but liquidation is mechanical. When the market stops making sense, you need to follow the process.
Anyway, I personally prefer to earn a little less rather than gamble on the network and luck near the red line...
As for whether "adding collateral" or "repaying debt" is more convenient, how do you usually choose?
