A week ago I wrote about the energy audit. Who in your life gives you energy, who quietly takes it, and what to actually do about each one.
A lot of you wrote back. And buried in the replies was the same question, asked a dozen different ways.
Is this a boundary I need to set, or am I just putting up with something I should let go of?
It is a better question than it looks. Most of us use the words boundary and toleration as if they are the same thing, and they are not. They are two different tools for two different problems. Reach for the wrong one and you can work hard on something for months and end up more drained than when you started.
This is especially true if you are a high performer. We are very good at one thing that quietly works against us. We absorb. We handle it, carry it, tough it out, because absorbing is part of what got us here. I am as guilty of this as anyone. For years I called it being low-maintenance. It was not low-maintenance. It was a backpack I kept loading and never set down. So when something starts to drain us, the first instinct is to take it on rather than address it, and that instinct makes us reach for the wrong tool almost every time.
Let me give you the simplest way I know to hold the difference.
A toleration is the backpack. A boundary is the door.
One is about the weight you are already carrying. The other is about what you let through in the first place.
What a toleration is
A toleration is anything you walk past, day after day, without resolving. The drawer that sticks. The contract you keep meaning to renegotiate. The email you have reopened nine times without answering. The standing meeting nobody defends. The promise to yourself about your mornings that everyone else's priorities keep overwriting.
Each one looks too small to matter. That is exactly why it does.
Every unresolved thing is a small, quiet withdrawal from your energy account. Not because you are consciously thinking about it, but because some part of you is. Your nervous system registers every unfinished thing it passes, every single time. Carry thirty or forty of those in the background and you are running your whole life on a battery you never see the readout for.
Here is the part most people miss. A toleration has exactly two honest exits. You fix it, or you genuinely accept it.
The drain does not come from the thing being broken or unfinished. It comes from the middle ground, where you have done neither. Where it sits there, unaddressed but also un-accepted, charging you a little every time you pass. Clearing tolerations is just the work of emptying that middle ground. Everything gets a decision.
What a boundary is
A boundary is not weight you are carrying. It is a line you draw about what is acceptable from here on.
Where a toleration looks backward at what has piled up, a boundary looks forward. A toleration asks, what am I putting up with? A boundary asks, what will I allow?
Boundaries are mostly about people and access. And for those of us who lead, they are also about protecting the one thing we cannot delegate, which is our attention. A boundary decides how others get to treat you, what gets access to your time, and what does not.
It only becomes real when you can name the line, say it out loud, and hold it when someone tests it. A boundary you keep only in your head is not a boundary. It is a preference you never told anyone about.
Where they overlap
Here is where the confusion lives.
Most tolerations are objects or tasks, and they have nothing to do with boundaries. A sticky drawer is not a relationship. But some tolerations have a face.
The colleague whose comments you keep letting slide. The client who treats your team badly. The friend who only calls when they need something. These land on your list too, but they are a different animal. For an object, fix it or accept it both work. For a person, only one of those is real, and the fix is not a small task you knock out before lunch.
The fix is a boundary.
A relational toleration is almost always a missing boundary wearing a costume.
So here is the test. If the thing draining you is a person and their behavior, you almost certainly need a boundary. If it is an object, a task, or a promise to yourself, you need a decision. Fix it or accept it.
The two mistakes
Once you see it this way, the two common mistakes get obvious.
The first is trying to accept your way out of something that actually needs a boundary. The colleague keeps taking the credit in the meeting, and every time you decide to rise above it. You tell yourself you are being easygoing, choosing peace, picking your battles. What you are really doing is deferring a hard conversation and calling it maturity, while the resentment grows underneath. Six months in, you can barely stand to be in the room with them, and you still have not said a word.
The second runs the other way. Trying to set a boundary with something that just needed a decision. You cannot negotiate with a sticky drawer. It does not care about your line. It needs a screwdriver or a shrug.
How they fit together
The two are not rivals. They are a sequence.
Tolerations are the audit, the full and honest accounting of everything draining you. Boundaries are one of the tools you use on the items that have a face. You empty the backpack first, giving every item a decision. Most of them resolve right there. The ones that do not, the ones where fix it turns out to mean a conversation you have been avoiding, are the ones that graduate into boundary work.
Clearing tolerations is the sweep. Boundaries are the locks you fit afterward, so the same weight does not pile back up.
Over the next two weeks, I am going to take each one in turn. First, how to actually empty the backpack. Then, how to draw the lines that keep it empty.
But you can start today with one question, the one that sorts almost everything.
Is this weight I am already carrying? Or a line I never drew?
Name which one it is, and you already know your next move. A decision, or a conversation. The backpack, or the door.
If one thing came to mind the moment you read that question, the person, the decision, the line you never drew, that is the one to start with. Hit reply and tell me which it is. I read every response.
And if you are carrying more than you want to be, this is the work I do one on one with founders and leaders sitting in exactly this spot. I stayed in the middle ground on the biggest thing in my life for six years before I finally moved. You do not have to.
