When You Have A Problem And Solve It Using Regex You End Up With Two Problems

That brief, shining moment when regex finally clicks in your brain and you feel like you've unlocked forbidden knowledge. You spent three days reading Stack Overflow answers, watched twelve YouTube tutorials, and now you can parse email addresses with a 47-character expression that looks like your cat walked across the keyboard. The enlightenment lasts approximately 6 hours before you realize you can't read your own regex anymore and it breaks on edge cases you didn't even know existed.

Fun fact: Jamie Zawinski's famous quote goes "Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems." Turns out he was being generous with that number.
