Who arranges Ethereum's blocks—do validators do it themselves? Don't panic, your class rep is here:
Whether to use MEV-Boost is up to each validator. Validators who don't use it can still build blocks with their local client.

Learning this won't make me money right away, but it can help me avoid making one more rookie mistake.
