Beforehand:

One approach to setting boundaries is simply to tell yourself what you will do and say beforehand. Now, this can be tough sometimes. So, it is critical to talk to yourself or with some friends. You have to check in periodically and make sure you have a plan each day, week, month, hour, moment, or however often as you want.

Be Ready To Say No

It is critical to be prepared to say no as that is a way to set a boundary. That does not mean you have to say no. You can allow yourself to change your mind to say yes. But it can be harder to stop yourself from saying yes in order to say no in order to enforce your boundaries.
