How much do you trust habit over the plan?

There's a piece going around about companies running on habits, not processes, and it hit me because storm chasing is the same. I follow the models, I have my route, and then the sky does something and I bail because it feels wrong. It usually works out, but I can't tell if that's skill or just stubbornness. Do you have a thing where your routine quietly overrides your decision-making, and you only notice it later?
