When I first started playing on the blockchain, I saw the flashing price differences in the pool and was excited: Wow, an opportunity has come.

Later, after being sandwich attacked a few times, I realized that what I saw as "meat" might actually be the transaction fees others are waiting to collect, using me as the sandwich filler.
Now, before I click confirm, I always take a screenshot as proof, even though I don't know who I can argue with… Anyway, it makes me feel more at ease.

These days, I see everyone complaining about validators/miners earning MEV and unfair ordering, and I can't help but criticize while also being realistic: that's how they make their income, retail investors can only be less of a prey.
Recently, I set limits and slippage warnings for myself, and after setting them, I really felt a bit more relaxed, like pulling my hand out of a hot pot…
Although it also reduces opportunities, it also reduces anxiety.
If I can avoid rushing, I won't rush; that's how I’ll start.
