When the numbers came in different from my forecast, I didn't panic. I opened the model, found which assumption was off, and adjusted it in ten minutes. My forecast isn't a fixed promise anymore, it's a living thing I trust because I know exactly what's inside it.
More people experience this than they realize.
You forecast with models you trust and quietly update as the real numbers come in.
