That "mobile fryer" situation is exactly the problem. That smell means the oil is breaking down and leaving a gummy, sticky residue everywhere it touches. It coats the inside of the fuel lines and the injector nozzles, and when it gets hot in the engine, it basically turns into varnish. You might get away with it for a little while, but then the engine starts running rough because the fuel spray pattern gets all messed up. It's a total pain to clean out.

But does a badge color honestly matter that much in real work lol. Most clients just need clear drawings, not some perfect scorecard. I've seen clean drafts with zero green badges and messy ones covered in them, so maybe we're overthinking this.

No way you said giving up was just being scared, that's wild lol. Most people blame busy schedules or bad memory, but admitting it's fear hits different. Your friend's commute trick is smart though, makes it less scary when it's just background noise at first. Honestly I might try that with Italian, because big classes make me panic too. The part about simple jokes sticking makes sense, it's not just grammar rules floating in your head.
