Immortalized as Davy Crockett in movies and frontier folklore, David Crockett was a ‘coonskin cap-wearing former-U.S. Congressman from Tennessee. He was killed on March 6, 1836, at the Battle of the Alamo, fighting for Texas independence. Crockett’s mantra, well-known during his life, was: “Be sure you’re right, then go ahead.”

It’s a mantra to which many of us can relate, encouraging us to forge ahead with confidence against any leadership challenge. But, the key portion of the phrase we must examine is this: “Be sure you’re right.”

For any disagreement with others, you must first consider that you might be wrong. Whether it’s with a family member, a team member at work, or our boss, when we disagree about something or don’t seem aligned, you need to start with humility. The biggest obstacle to keeping the ego in check is the inability to detach. You must be able to detach.

Don’t fall into the trap of assuming the other person is wrong and you’re right, so you can forge ahead with self-righteous indignation. Consider that you may, in fact, be wrong.
