I’ve been thinking about this question recently (thanks, Danielle).
There’s a lot of freedom in giving up on a matter of principle, so you can move on with your life.
When at an impasse in a difficult situation, the freedom comes in saying “OK, whatever. Have it your way, but let’s stop the silliness.”
Letting go is tough, though… because you’re right. And you want everyone to acknowledge it! But there’s a price to pay for being right and receiving the acknowledgment.
“Life is too short for this” is a great mantra for conflict management.
Do you need to be right all the time? Maybe it’s better to just be free.
