Treat everyone equally, regardless of their status or authority.
Avoid being overly reverent of authority figures. Understand that even those with experience and authority can, and do, make mistakes.
In Jiu-Jitsu, don’t always assume instructors or senior students are right. Be willing to ask questions and challenge ideas. Be willing to listen to, and learn from, students less experienced than yourself.
Avoid gyms where black belts and instructors cannot be challenged.
