This is a part 2 of an ask I answered earlier! Linked here, the second question answered below the cut. It's not exactly a guide or a how-to but more a better in depth look at what you're attempting to achieve.
Self-programming for beginners:
Firstly, and this is the annoying step, I recommend research. There are SO MANY forms of programming, simple & complex, built off of each other, reliant on certain circumstances, etc. you should be doing proper research over what you want to know and what you want to accomplish. I also recommend looking more into Pavlov and behavioral scientists, they can teach you about reward and punishment responses and better ways to train the brain.
Additionally, I recommend looking into scripts and triggers. Programming scripts are incredibly common, they give a baseline of information, the alters you want to form, their purpose, their triggers, what tells them what to do and how to behave (side bar: if anyone wants me to write some scripts I would 100% be down, I find them incredibly interesting.)
Programming yourself without an outside handler takes dedication and practice. Firstly I would recommend setting goals, associations, punishments and rewards. You should be able to break your behaviors down into base actions based off of what you want and are trying to achieve.
I also recommend splitting internal handlers. Alters who's jobs involve holding yourself accountable. They will punish alters who misbehave, keep track of the expectations of the body and force everyone to do as their told. It's harder to hold yourself accountable and force your system to do what you want without these types of internal handlers.
Try to keep constant track of everything you do and where it fits into your programming. A document or a journal will work best. This will allow you to control informant alters (so that they can better tell your handlers and punishers if someone did something wrong).
I personally recommend doing this when you're experiencing high stress, the structure during stress will make your brain more attached to the programming. Some people are not as stress and trauma oriented so you don't have to, but it's a really good way to make sure your brain will do what you want.
Remember that programming is a violent/traumatic thing, you cannot become programmed without the stress of it, it will never be peaceful and easy but if it's your desired outcome you must be prepared.
