Recently, I've been thinking about "sandwich/arbitrage" again. Honestly, you think you're spotting an opportunity, but often you're just giving others a fee. Especially on-chain, once slippage is triggered, the next second the transaction price gets pushed away. The mindset can really get heated: clearly you clicked to confirm, but it feels like someone tapped you from behind.

Retail traders complain that validators eat MEV and that the ordering is unfair. I understand, and it's normal to curse a bit. But now I see it more as a practice exercise: every time I want to chase, I first ask myself whether I'm profiting from the information gap or just working for the faster players. Anyway, I prefer to do fewer trades, practice slowly without rushing, and if there's not enough evidence, I just pretend I didn't see it.
