Ok I came across The Art of War and I found the 5 qualities of a good leader. When I read it I thought these qualities were also to be found in a good Dom. They are
Intelligence - the ability to plan and know when to change effectively
Trustworthiness - means to make people sure of punishment or reward
Humanness - means love and compassion for people, being aware of their toils
Courage - means to seize opportunities to make certain of victory without vacillation
Sternness - means to establish discipline in the ranks by strict punishment
Maybe I'm stretching it a bit but I think qualities can be applied to BDSM. What do you think?
