Just as my phone vibrated, the transaction failure popup also had a red dot, and my first reaction was "Is it lagging again?" When I clicked in, I realized I was anxious: the slippage was set too tight, and the pool depth wasn't enough. I still hurriedly confirmed that one click, only to be lifted out... Basically, I brought the habit of "wanting to grab the front row" into trading.

Reflecting: For such thin liquidity pools, don't use a single slippage template blindly; look at the depth before placing an order, and splitting into two trades is more stable than going all-in at once. Also, timing is really important; when the market jumps, thinking you save a second actually makes it easier to get the worst price. Recently, there's been talk about NFT royalties again, and when secondary liquidity shrinks, many pools become thinner, and orders/trades become more volatile. Don't fight yourself... For now, I'll try to be a half beat slower next time.
