As a Rotarian, I follow our 4-Way Test. In all things we say and do, 1. Is it the truth? 2. Is it fair to all concerned? 3. Will it build goodwill and friendship? 4. Will it be beneficial to all concerned?
I believe that's our 4-Way Test (writing it down from my memory). You can't be truthful unless we accept our own responsibility in any business (or personal) relationships.
