Always Take Backups Of Your Database

That moment when your "quick fix" SQL query has been running for 10 seconds and you suddenly realize you forgot the WHERE clause. The hamster perfectly captures that split second of pure panic when you connect the dots - your simple update is now wreaking havoc on every single row in production. Time slows down as you frantically reach for Ctrl+C while simultaneously having an out-of-body experience where you see your entire career flash before your eyes. The backup you didn't make last week suddenly feels like a really critical life choice.
