I muted the group, and the world suddenly became much quieter...

In the past, every time I refreshed, it was "MEV is squeezing me again" or "the ordering is unfair" arguments everywhere, which made me annoyed and also itchy to chase after.
Only when I calmed down did I realize that the most frustrating thing at the end of the year isn't losing or making a profit, but that you simply can't recover your trading flow: cross-chain, aggregation routing, the slippage eaten when you get squeezed, all need to be reconciled later.

My current simple method: for every large swap/cross-chain transaction, conveniently save the transaction hash, the route used, and screenshots of the expected/actual received in the same folder, then export a CSV backup on the weekend.
Don't expect to manually scrape them from the browser at the end of the year; you'll really start questioning life...
Anyway, I first treat "being reproducible" as the baseline, so at least when reporting, I won't be full of question marks.
