Your mind can become a prison without ever building a wall.

Confinement does not require anything physical. Rules you never examined, roles you agreed to at twenty, and predictions about how people would react can hold you in place more effectively than any barrier, because you enforce them yourself and never notice doing it. The limits feel like the shape of reality rather than the shape of a habit. There is nothing to push against, which is exactly what makes it hard to see.

Name one rule you obey without knowing where it came from. Something you would never do, or always do, that you have never actually justified. Test it in a low-stakes way and watch how much of the wall was made of assumption.
