Why do breakdowns and targets still run me if I can run production?

You said it yourself: you can run production. That was never the question. The question is why breakdowns and targets still feel like things that happen to you. This is not a floor problem. Machines will keep breaking. Numbers will keep moving. That will not change, and you cannot make it change. What can change is this: right now, nothing stands between you and the chaos, so every problem lands on you fresh, as if you had never seen its kind before. A person who stays ahead does not have fewer breakdowns than you. They have already decided, before the shift starts, what they check first, what they let wait, and in what order they act when something goes wrong. You have not decided this yet. That is the whole gap.
