No wise pilot, no matter how great his talent and experience, fails to use a checklist.

Insight: The temptation when you're good at something is to trust your instincts and skip the boring steps. You've done this a hundred times. You know what matters. Why waste time on a checklist? But here's what experience actually teaches: the better you get, the more catastrophic your mistakes become when you finally miss something. A surgeon who's performed a procedure thousands of times can still leave a sponge inside a patient. A pilot who could land blindfolded can still forget to lower the landing gear. The checklist isn't really about catching rookie mistakes. It's about humility at scale. It's an admission that your brain, no matter how sharp, operates within limits. You get tired. You get distracted. You pattern-match to similar situations that weren't quite the same. The checklist is your system fighting back against these very human failures that experience actually makes more dangerous, not less. What's surprising is that using a checklist doesn't feel like strength—it feels like admitting weakness. But that's exactly backwards. The person disciplined enough to run through the basics every single time isn't less confident in their abilities. They're confident enough to know that confidence alone isn't enough.
