People are talking excitedly about modularization and the DA layer narrative, but users should actually care more about: don't treat your wallet as paper. The mnemonic phrase is essentially the key to all your assets. Any "customer service / airdrop registration / wallet synchronization" that asks you to fill in words, just block them directly—don't make excuses for yourself.

And regarding signature authorization, the sneakiest thing isn't transfers, but those "free claim / verification" prompts that make you click once, only to give away unlimited authorization effortlessly. My two red lines are: avoid connecting to unknown sites; don't sign signatures you don't understand—better to miss out. If you need interaction, use a small wallet first, keep assets and interactions separate, so you won't cry when checking the blockchain later. Anyway, if you can avoid paying tuition, don't pay it.
