Sometimes you get into a discussion with someone else, and it becomes apparent that he or she is absolutely convinced of their position or opinion.
They may be listening to you, they may even be saying that they’re open-minded …
… but when it comes to actually entertaining a different position, that’s just not possible for them.
In these cases I think it’s best not to try harder to convince them otherwise.
Rather, just to accept it.
Accept that they are right, at least for them, without judgment.
There’s no need, or value added, for you to attack further.
On the other hand, if you can stand there and admit that ‘their position might be true or correct’, then, without accepting it as your own, you’ve opened the door for them to take step closer.
Whenever they are ready.
