Punishment, and praise.
What works better for training your slave. A slave by nature wants to do a good job serving her Master, if she doesn't you have deep problems, but were not going to look at that right now, lets look at the normal happy slave, that is happy to be with her Master, or Mistress.
You leave for the day, and give your slave the task list, and you expect it to be complete, you didn't give the slave a full task list, you figure out some down time for them to eat and watch some TV or screw around on the internet, but when you come home, the list wasn't completed.
Of course you have to ask the question, "What happened", just in case the house burned down, and they rebuild you a entire new house, but forgot to add the extension that you always wanted.
Well, Sir, I was blogging on the computer and I lost track of time. Ok, you think to yourself, time to have fun. Ok, no computer usage for 2 months, and that old wind up alarm clock you have to wear it around your neck for a week, so that way you won't lose track of time. (Like I said, have fun with it).
The next day, your heading out the door, and she/he has there task list, and there looking like a rapper from the 80s with the dam alarm clock around their neck. When you get home, the tasks are complete, plus, your slave thought on there own, and did additional items, that you didn't have to point out.
You praise them for doing a great job, but what about the other stuff they did? That's what your training them for long term, to think on there own. In the end of training, you want your slave to be free thinking, knowing what you would want done, and doing it. So you have to do a special reward, a positive motivator to keep them going in that direction. As Master/Mistress you give punishment, and you can take it away too. Dam, we have super powers.
So you point out to slave, the extra stuff that they did, and then praise them for it, and remove a few days off the computer ban, as a special reward. Now, if everything goes right, maybe with the positive reinforcement you did today, it will sink in, and the same thing will happen tomorrow with rapper Sir Slavealot. (Ye think I would remove that clock, hell no, I would make them go food shopping for the week wearing that dam thing)
Now if you can make punishment special, make it special, but only for a dumb screw up, like I pointed out above, not for something minor, that what lines are for. What are some punishment that can be special. Well let see, they played with themselves without permission and came, and you have them on lock down. What you want to do is start a playtime, something lite, and if they have a favorite toy, like a vibrator, starting running it up and down there leg, then whisper into there ear, you punishment for cumming with out permission is this, we will not be using this toy in playtime for the next 2 months, and toss it to the floor or lock it in a draw.
It sounds mean, but guess what, you corrected the problem, but it also gives you something that you can reward with too, as a training tool. Yuppers we are mean bad asses. That's why we wear leather, and we take toys away from helpless slaves.
Also if by some dumb luck, you have the perfect slave, and they never screw up, you can use the above and revere it for rewards. For example, you come home, the house is perfect as always, the welcome home rituals perfect as always, dam, this is getting me sick
so you call for a lite playtime. This time you work your slave up to the point there begging for release, then you reach into the draw, and pull out a new toy as a reward. You show it and give it to them and you finish them off with it.
Ok, next, i'll get into the deep seated problems
