In the past, I would pretend to be dead when I was a little away from the liquidation line, thinking "It probably won't happen"... But one injection of collateral cured me. Now my habit is: when I see the health score is only three steps left, I treat the position as already lost and immediately do two things—either add some collateral / repay some debt to catch my breath; or directly reduce my position, don't fight the system head-on. Don't expect to operate at the last moment; with on-chain congestion + slippage, no matter how fast your reaction, it's like chasing a cat's tail.

Recently, the "compound yield stacking" of pledge and shared security has been criticized as a copycat scheme, and I also resonate: the more you stack, the more the liquidation line looks like a hidden line. It looks pretty during normal times, but when things go wrong, it's a chain reaction. Anyway, I now prefer to earn a little less and keep a "withdraw at any time" option, for now.
