Just say “okay”
Sometimes to keep things moving, you have to just say “okay”. There are many situations that warrant a response, push back or the insertion of more information so that the other person can see your point of view. There are other times when we just need to say “okay” and move on. No every battle needs to be fought; as tempting as it may be (particularly when you KNOW the other person is wrong).
My reason for saying this is that there are just some people that won’t budge. They are rocks; pillars of stubborness, piles of strength. . .okay, you get the picture. They won’t agree or change their minds no matter how much information is presented. And then there is you, on the other side wanting to scream, shake them uncontrollably and beg them to listen or just use some mystical powers to change their mind. No matter where you fall, you have a decision to make. You can continue to stay and argue your point, or you can choose to say “okay” and move on.
You’ll have to keep the goal in mind. This is what should determine how much time you spend trying to convince the person that you are right. If all goals can be met (albeit more slowly or slightly more difficult) and that person can interrupt that, it’s best to keep the goal in mind, so okay, get it done and say NEXT!
