It is better to stick to one Autosuggestion program at a time. You can give yourself affirmations for two topics only if they are related. For instance, it is fine to take up two Autosuggestion programs – one for removing stage fear and the other for reducing general anxiety because they are related to each other. But if you want to give affirmations for procrastination and removal of nail biting, it is better you deal with one issue first and take up the second after a few days.
Even in case of related issues, it is very important that you give each topic a seperate sitting and also give a gap of atleast two hours between each sitting. For instance, if you are doing an Autosuggestion session for stage fear, then give a gap of two hours or more before doing an Autosuggestion session for anxiety reduction.
