Fortress Mindset
A mind under attack builds walls. Reasonable enough — until you notice what walls do: they keep the enemy out and the occupant in.
The pattern is everywhere. The company that stops listening after a crisis. The person hurt once who now audits every friendship for danger. The group that treats every question as an assault. Each was wounded; each fortified; each now lives in the fort, which is comfortable, defensible, and very small.
The tragedy of the fortress is that it cannot distinguish. The same wall that blocks the invader blocks the messenger, the new idea, the apology, the rescue. A wall is a yes-or-no device in a world that mostly needs a filter.
So if you catch yourself fortifying — after the betrayal, the failure, the public mistake — build gates instead. Close them when needed, but build them to open. Security that cannot admit help is not security. It is a prison with the keys on the inside, and the sentence is self-imposed.
