Sometimes, sending transactions on-chain is like catching a taxi during rush hour; you toss your order into the mempool, which is basically a waiting queue. When the network is congested, miners/validators will naturally pick the ones that pay the highest tips first, and yours might get pushed to the back, bumped around, or even expire after waiting for a long time; what's more frustrating is that if you get anxious and resend with a higher fee, your previous transaction is still pending, causing a conflict with yourself, and wasting fees in the process.

Recently, those new L1/L2 projects offering incentives and pulling in TVL, everyone rushes in like a swarm. Old users complain "mining, extracting, selling," which I can understand: when congestion hits, costs and emotions run high, and the entire execution process gets distorted.

I'll first revoke any unused authorizations in my wallet to avoid messing up when in a hurry.
