Resilience or Stubbornness
They look the same from the outside. Someone refusing to quit. The difference is on the inside, and it matters.
Resilience adapts. It keeps the goal and changes the route. When the wall doesn't move, resilience looks for the door. It absorbs the hit, learns from it, and keeps going in a smarter shape.
Stubbornness just repeats. Same approach, harder. It mistakes effort for progress and pride for principle. Stubbornness will run you straight into the same wall a hundred times and call it grit.
I've been both, and I can't always tell in the moment which one I'm running on. So I ask a question. Is this working? Not is it hard, not am I committed, but is it actually moving? If the answer is no and I keep doing it anyway, that's not resilience. That's ego wearing a costume.
Resilience listens to reality. Stubbornness argues with it. The strong move is usually the one that requires admitting the old way isn't working and trying something else. That takes more spine than just gritting your teeth.
