I was thinking this morning that a Master should lead with an open hand not a closed fist. When you are open to understanding your slave/sub then she will serve better out of desire and not fear.
I also feel a Master can react to joyful moments. Things that are exciting and spontaneous. But when it comes to punishment a Master should only act and not react. I say this for you need to be in control realizing the action needs to fit the punishment. Reacting may lead to regret later, where acting solves the problem so it is likely to occur again.
