You become harder to trap when you stop waiting for everyone else to behave correctly.

Depending on other people to act correctly puts your outcomes in their hands. It also leaves you defenceless when they do not, since your whole plan assumed they would. Building around what people actually do, rather than what they should do, makes you far harder to corner.

Look at a plan you are relying on and ask what happens if a key person behaves poorly. If the answer is that everything falls apart, add a fallback. You can still hope for good behaviour while not requiring it.
