Last night, the network was a bit congested. I was watching my cross-chain pre-transaction queue in the mempool, like a food delivery order stuck with "rider has accepted the order" but not moving... Basically, the fee you paid wasn't enough to "grab a spot," and miners/validators are more interested in more profitable transactions. The more I waited, the more anxious I got, especially since the bridge's time-limited window was counting down. If I got stuck in the middle, it would be very awkward.

Later, I remembered the time I didn't understand something and didn't act on it: a certain on-chain yield product was compared with U.S. Treasury yields and RWA. I was overwhelmed by all the jargon at the time and wanted to jump in and harvest, but when I saw a long chain of contract calls plus mempool congestion, I hesitated and closed the page... Looking back, it's good I didn't push through. Anyway, when there's congestion, I usually do two things first: either increase the fee a bit but set a cap, or just wait until the chain isn't congested anymore—it's more hassle-free.
