Talk more, talk better. Business revenues can double or triple as a result of better communication and cooperation between family members. Respect other family members' opinions to increase harmony and collaboration. Learn how to talk to one another through difficult and emotional issues, instead of yelling or bailing.
Set up structures that assist management and decisions. Thorny issues should be isolated and addressed in an appropriate forum. A Rhodes scholar might feel justified in questioning the credibility of a cousin who couldn't hack it at junior college, but a public showdown won't help anyone. Family councils and assemblies can be a safe environment for "family-only" business. Advisory boards add an often-needed surge of objective expertise.
