I found that the hardest part of lending is not choosing which pool, but watching the liquidation line—the red line... When I'm three steps away from it, I usually do three things first: copy down the position and collateral/debt ratio (don't rely on intuition), then reserve the collateral I can add and stablecoins I can repay, and finally calculate the worst-case scenario of "if it drops again / liquidity is withdrawn" step by step. Basically, it's about pre-positioning fire extinguishers within reach.

Recently, the "yield stacking" of staking and shared security systems has been criticized as a copycat, but I actually want to remind myself: the more layers you stack, the more the liquidation line becomes like a suddenly narrowing doorframe—just a little squeeze and you'll get stuck. And I need to be reminded: don't wait until there's only one step left to add to your position and increase collateral—that's when you're already getting emotional. For now, I'll do this, and later I’ll review my liquidation threshold table again.
