Today I saw someone post about "on-chain arbitrage opportunities" again.

My first reaction wasn't envy, but rather thinking: am I the one eating the meat in this deal, or the one just providing the bread for the sandwich...
You might think it's an opportunity, but it could just be someone charging an extra layer of fees + your slippage combined.

Would I also jump in?
Yes, but only if I can handle being squeezed.

Anyway, right now I'm more concerned about the mindset at the moment of placing the order: rushing to complete a trade = easier to be targeted.
Recently, with staking, shared security, and yield stacking being criticized as copycat schemes, I can understand.
The returns look impressive when stacked, but the risks are really stacked up too.
My little habit remains the same: keep positions small, only do what I understand, miss out if I need to—don't treat the market like a wishing well.
