What is Jack's core teaching about problem-solving?

That the rules others follow are constraints you can exploit. He operates in systems — pirate codes, naval law, merchant customs — that others treat as fixed. He treats them as terrain: some parts are obstacles, some parts are tools. The rules governing his enemies are as useful to him as his own abilities.

What does Jack model about flexibility?

That the goal is fixed; the path is negotiable. He always wants the same things (freedom, the Black Pearl, rum). The specific method for getting them changes with each situation. Most people have the opposite problem: they have a fixed method and wonder why it stops working as situations change.

What does Jack teach about reading people?

That most people's behavior is predictable from their stated values. Barbossa follows the pirate code even when it's inconvenient, because he built his authority on it. Norrington is bound by naval honor. Elizabeth is bound by loyalty. Jack builds his strategies by finding the specific thing each person won't break — and organizing his plan around that fixed point.

What is Jack's most practically transferable lesson?

The question he asks before any situation: What does everyone in this room want, and how can I position myself between them and it? He doesn't need to provide what they want — he needs to control the path to it. This is how he negotiates from apparent weakness: he positions himself as necessary.

What is Jack's deepest insight?

That freedom is not the absence of constraint but the ability to navigate constraints more cleverly than they constrain you. He's always in some form of constraint — debt, capture, curse, pursuit. He's also always more free than anyone around him. The constraints are the game. Getting out of the game is not the point; playing it better than anyone else is.
