Anyone can guard the door to the club. Leaders are the ones holding it open.

Gatekeeping is easy and feels like standing for something. Deciding who is not good enough, not serious enough, not one of us requires no skill and produces a smaller, more anxious group every year. The harder position is making room for people who are not yet impressive and letting them become so inside the group rather than before entering it.

Look at who is hovering at the edge of something you belong to and invite one of them in properly. Give them a way to contribute in the first week. If the group is worth being in, it can survive new people.
