On the wrong train? Get off at the next stop. Riding to the end out of pride costs extra.

Pride keeps people moving along paths they have already recognised as wrong. The cost of stopping grows the longer you stay on, and the reasons for continuing get more elaborate as they get weaker. Admitting a mistake early is far cheaper than defending it late. Nobody is keeping score on the exit.

If you already know something is wrong for you, name the next reasonable stopping point and take it. Tell one person so the decision has a witness. Turning around is uncomfortable for a short while; finishing the wrong trip takes much longer.
