The Fenzy article was brilliant, however before this there seems to be a shared opinion that it is hardly a subs fault, and that a dominant should automatically be working to fix the problems of a poor submissive - ask yourselves, why?
As for not having enough patiences, and looking for a gift wrapped partner; patience need only be spent where there is potential. Otherwise it is a waste of time and effort. Some subs don't want to change, as they aren't really suited to the life or role of a submissive, they just take the notion as romantic or erotic, but will never be able to carry through.
A good dominant cannot fix all the problems in a bad sub, sometimes, a bad sub will always be a bad sub.
Sometimes problems can be overcome, but the base material must be there.
I have to say, in most D/s relationships, the dominant is not expected to be the ultimate teacher, with the sub blinding following. There is a dymanic, an equalibrium, which both must work for. A sub cannot just sit on their haunches and wait for the dom(me) to overcome things.
This entire idea is absurd, some people (who make bad subs) become one simply because they are too lazy or scared to make any decisions or effort in their life.
That problem cannot be overcome, except by the sub themself.
