How do I handle the fear of upsets and safety incidents at the plant?

You've learned to run the operation, and yet the upsets and safety incidents still frighten you. That fear is not weakness. It's the mark of someone who understands what's actually at stake. The day that fear disappears entirely is the day to worry, because it's what keeps you sharp. The goal isn't to stop being afraid. It's to turn the fear into readiness. You can't prevent every upset, but you can know your responses so well that when something goes wrong, your training takes over before the panic does. Fear that has a plan attached to it becomes focus. Fear with nowhere to go becomes dread. So put your fear to work. Pick the scenario that scares you most and walk through it, step by step, until your response is clear and practiced. Do the same with the next one. You're not trying to feel calm by pretending nothing can happen. You're earning calm by knowing exactly what you'd do if it did.
