I'm a bit paranoid; I used to always say "I only look at on-chain data," believing that data wouldn't lie.

But when it came to actually placing orders, I couldn't hold onto spot positions, and I would easily get itchy to open large positions on futures, eventually either making a small profit or getting liquidated—it's pretty embarrassing...

Later, I translated it into a simple phrase: Don't let one trade determine your mood today.
Position size is like my backup mnemonic phrase; even if it's troublesome, I prefer to layer it: if I want long-term, I lock it away as if it doesn't exist; if I want to tinker, I use that small amount of money that "won't affect my sleep even if I lose."
Especially now, with new L1/L2 chains frequently issuing incentives to attract TVL, people are both "mining, selling, and cursing," and I become even less willing to treat short-term trading as long-term.
Anyway, stay alive first; only those who can hold onto their positions truly deserve to call it a position.
