This exercise avoids the language of self-care, never recommends cutting anybody off, and treats a yes you chose as a yes worth keeping.

Nobody agrees to things for no reason. Remove the payment without naming it and the limit lasts a fortnight.
A yes you chose is not a boundary problem. Some of it is worth the cost.
What you'll explore
A note from Mark

Most advice about boundaries is written as though the difficulty is knowing what you want. It rarely is. The difficulty is that saying yes is buying something, and nobody tells you what you are giving up when you stop.
So I would start there. Peace, approval, being the one who can be relied on, an income, not having a conversation you do not want to have. Once you can name it, the limit gets much easier to design, because you know what you are trading.
Then I would get specific about who. People arrive saying they cannot say no and it turns out they say it perfectly well at work and never once to a brother. That is not a personality trait. It is a relationship with a history.
And I would only ever set one. A list of boundaries is a way of having none, and the one you can hold on a bad Tuesday is worth five that read well.

What now?
01 · Save it
Where the yes is being given, specifically.
02 · Test it
Change what you do at the point of the ask, not what you explain afterwards.
What I would do
Find out what the yes buys before removing it. Nobody agrees to things for no reason.
Get specific about who. Most people who describe a general problem have a particular person.
Describe the limit as your own conduct. Anything that needs the other person to agree is a request.
One limit. Lists of boundaries are a way of having none.
Leave a chosen yes alone. Plenty of the work you resent is worth doing anyway.
Test it
Ask whether the yes is chosen. If it is, protect it and stop.
Ask what you get from agreeing. If you cannot answer, you have not found it yet.
Check whether the limit needs anybody's permission. If it does, it is a request.
The alternative
The obvious conclusion is that you need better boundaries. Often the evidence says something narrower. Sometimes this is not a general difficulty at all, it happens with one person and started when you became the reliable one. Sometimes the yes is buying something you would not want to give up, and the honest answer is to keep paying knowingly. Sometimes the problem is the volume of work rather than the absence of a limit, and no amount of saying no fixes an impossible load. And sometimes the limit you need is not with another person but with yourself.

The book that put the word into general use, and it carries a strong prescriptive tone that will not suit everybody. Take the part that lasts: the distinction between what is genuinely yours to carry and what you have taken on because nobody else would. That question does more work than any amount of language about limits.
