An interesting anecdote, from a leadership meeting I had with a team. We were throwing around names for another group leader. The names are changed to protect identities.
I suggested Tracy, a hard worker and a talented athlete.
The head coach spoke up: “It can’t be Tracy. I mean, Tracy still hangs out with Joelle.” The assumption, which everyone at the table understood, was that Tracy couldn’t lead her teammates if she was still hanging out with someone as immature as Joelle. That spoke to Tracy’s own immaturity.
Everyone nodded in agreement, the team left with less leadership than was needed.
