My current idea is: if your position is three steps away from the liquidation line, there's no need to hold on stubbornly. Just focus on "staying alive" first, even if it means earning less. Because once you're close to the red line, your mind is only left with praying, and all operations become distorted.

I usually first pay back some of the borrowed amount or add some margin to push the liquidation price further out, leaving room to sleep peacefully; then I avoid selling the things I least want to sell, instead I deal with assets with poor liquidity or thin order books first, to prevent a real emergency from making you unable to sell when you want to. Then I set the alert line more conservatively, so the system doesn't make decisions for you.

These days, there have been cross-chain bridge hacks and oracles giving erratic quotes, everyone is just waiting for "confirmation"... Honestly, the more these situations happen, the less you should expect on-chain data to always be normal. Once liquidation is triggered, it won't reason with you. Anyway, I prefer to cut my losses early rather than be passively liquidated twice. That's it for now.
