Excellent points all.
Trust and trusting members to do the agreed upon thing
Equality and by this I mean every member must make a significant contribution, no slackers, freeloaders, or cheapskates.
The ability to say NO to people, even family who just expect you to help them. This might mean emphasizing your NO with force.
Skillset crosstraining - some people will be naturally better at some things but everyone can learn a little of everything.
I'm sure I missed a few things.
Thank you for the insight Goodburbon.
