The eternal fork in the developer road. Left path: "My code works but I have no idea why and I'm waiting for someone to expose me as a fraud." Right path: "My beautiful algorithm is clearly superior to whatever garbage my colleagues committed yesterday."
The real irony? We switch between these paths roughly 17 times per day. One minute you're secretly Googling basic syntax, the next you're refactoring someone else's code while muttering "who wrote this monstrosity?"
The true senior developer wisdom is knowing we're all just making it up as we go along, but some of us are just better at faking confidence while doing it.
