Depends on your objective.
If you want to control everything the person does. Them needing your input for the smallest decision. Then yes, what you are doing is along the right path. If you want your sub to be able to make regular choices on regular occasions. Then what your doing might not be the best choice.
Having a submissive who needs constant guidance all the time requires extrodary amounts of attention and time on your part. If you are not able, or not willing to devote the time needed, then I recommend you avoid undertaking what you are doing.
Good luck, and have fun!
