Last night, the blockchain was a bit congested. I was watching my transaction queue up in the mempool, feeling like going through airport security: you think once you're in line, you're safe, but in reality, someone can cut in front of you (with higher gas), or the line might suddenly switch windows (the block packing strategy changes), or your "boarding pass" might become invalid soon (nonce gets stuck or replaced). To put it simply, during congestion, the most frustrating part isn't the technology—it's the mindset: watching the confirmation delay, you start imagining "Am I being squeezed out?" "Did I choose the wrong route?"… then, with a shaky hand, you increase the fee or resend, ending up making things even more chaotic.

Recently, there's been a lot of talk about the lag in on-chain data tools and tagging systems. I now see it as a reference map: it can point you in the right direction, but it doesn't guarantee real-time traffic conditions, especially during congestion when it can mislead you more easily. Anyway, I treat this as practice—practicing patience, practicing not changing my mind too often. When I really need to act, I plan ahead for timeout scenarios; otherwise, getting emotional is more costly than the transaction fee.
