Why do the hard threat models still trip me up?
You can secure most systems without thinking hard. That is real skill, and you should not pretend otherwise. But the complex cases are not a harder version of the easy ones — they are a different task. Your instinct was trained on patterns. Complex threats often have none. The comfortable story is that you just need more experience and the gap will close on its own. Examine that. You are likely doing the hard cases the same way you do the easy ones — in your head, fast, trusting a feeling. The mind skips steps when the load gets heavy. It did not skip them on purpose. It skipped them because you let it work unchecked. The work in front of you is not learning more facts about threats. It is building a method you use on purpose, every time, especially when you feel sure. Write it down. Slow down. Let someone else try to break it. That is the whole discipline.
Because you are running on instinct built for familiar systems, and instinct breaks down where there is no pattern to match. The fix is not more years. Write the threat out: what you defend, who wants it, how they would get it. Test that writing against another mind before you trust it.
What changes unlock by starting

- You have a written method you can run the same way every time, even under pressure
- You catch your own blind spots before someone else does it for you
- You trust your judgment because you tested it, not because you hoped it was right
