Great teams get things done that matter . Some of my favorite teams that I have been on have been election campaign teams. We had a candidate that we thought could make a difference and we worked to that end. A friend of mine can't get anyone to be on his church's Board. One of the reasons may be is that they don't think they can change anything.
Impotency is the biggest danger to any team.
Once you feel impotent, you are just going through the motions and wasting everyone's time. I don't even know why people allow impotent teams to continue. It is like they like to share the pain. That is true in the church too. Great teams want to make a positive impact on the church and community.
