I once deleted the whole production kubernetes environment trying to fix an update to prod give awry, at11pm. My saving grace was that our systems are barely used between 10pm-8am, and I managed to teach myself by reading enough docs and stack overflow comments to rebuild it and fix the initial mistake before 5am. Never learned how to correctly use a piece of stack that quickly before or since.

Nothing focuses the mind more than the panicked realisation that you have just hosed the production systems
