Life involves a series of rules, according to the character Leroy Jethro Gibbs in the long-running TV show, NCIS.
One of those rules is Rule #6, “Never apologize, it’s a sign of weakness.”
Gibbs got it wrong.
It’s harder to admit a mistake than to deny you made it. So which action is the sign of weakness?
It’s not a sign of weakness to apologize. It’s a sign of strength. But that’s not the real reason why you must apologize.
