The cut
One situation, six pieces, two boxes. The exercise that trains the third line of the Serenity Prayer: the wisdom to know the difference.
Why a third answer is missing
Most exercises on this site ask you to label one thing. A proposition is true or false; a situation is yours or not yours. But real situations are rarely one or the other. They are made of parts, and the parts fall on different sides. Say "both" and you have named the problem without solving it.
A cut removes that escape. The situation is broken into six pieces first, and each piece takes one box. At the level of a piece, "both" no longer exists.
Where it comes from
Grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. The first two lines ask for attitudes. The third asks for a skill, and this is the exercise for that skill.
Epictetus opens his handbook with the same division, around the year 125: some things are up to us and some are not. He does not add that most events contain both, but every example he gives has to be taken apart before the division can be applied.
What to look for
Two mistakes come up again and again. The first is treating everything that is finished as not yours. Work you did last year is past and unchangeable, but it was your doing, and it was the only effort that counted. Unchangeable and not yours are not the same thing.
The second is putting your own reaction in the wrong box. That a remark stings is not yours; the first movement fires before you have a say. Whether you are still turning it over three hours later is yours.
Worked examples
Three of the cuts on this site, laid out in full. In the practice section they run one piece at a time, so you make the cut yourself before you see it, and every topic page carries its own three.
The situation
You are passed over for a promotion that goes to your colleague.
Yours
- Whether you let this decision devalue your two years of effort.The effort has been delivered and the outcome was never its measure. Whether two years of work become worthless because somebody else gets the title is a judgment, and you are the one who passes it.
- Whether you congratulate your colleague.Entirely yours, and probably the most expensive item on the list. Skipping it punishes nobody but you.
- Whether you ask what would have been needed.One question, yours to ask, with an answer you can use next time. That is the difference between being passed over and knowing why.
Not yours
- That the decision was made before you heard about it.A decision taken in another room at a moment you were not in it. You may have views about it, but it is done and it was never yours.
- What your manager thinks of your ability.A judgment inside somebody else's head. You can influence it and you cannot determine it, and only the second makes a thing yours.
- That your colleague is better at being visible.His quality, not yours. What is yours: whether you learn something from it or carry it as a grievance for years.
The reasoning. Notice what happens once the six pieces sit side by side. Everything that is yours lies in the future or in your own effort. Everything that is not yours sits in another person's head or has already happened. That is not a coincidence, it is the shape almost every disappointment has. Anyone who sees only “I was passed over” is left with one lump that nothing can be done with.
The situation
Your adult child has not returned your calls for weeks.
Yours
- How often you call and in what tone.Entirely yours, and the only dial on the whole panel. The question is not whether you may call, but whether you call to make contact or to collect a debt.
- Whether you voice your worry without wrapping a reproach in it.The same sentence can be an invitation or an invoice. Which of the two you send is yours to decide, and the other person hears the difference unfailingly.
- Whether you keep the door open without attaching conditions.This is the posture you wait in, and it is yours, again every day. Keeping the door open is not the same as giving in.
Not yours
- That he does not call back.The behaviour of another adult. All the pain sits here, and here is exactly where you have no say.
- Whether he approves of the choices you made.His judgment. You can explain, you cannot assign. And as long as you need his approval, you have handed him a key to your peace of mind.
- How many other people he does speak to.A fact about his life, not a statement about your worth. Reading a ranking into it means charging yourself a grief nobody handed you.
The reasoning. The temptation is to put the whole situation in the other person's box and wait. Cut it in two and three things turn out to be yours today: your frequency, your tone and your conditions. That is little, and it is exactly enough to make the difference between a door that stays shut and a door left ajar.
The situation
Your employer announces a restructuring and the names are not out yet.
Yours
- How many evenings you spend running scenarios.The unease arrives by itself; that is the first movement and nobody is blamed for it. Whether you keep it going for three hours is the second movement, and that one is yours.
- Whether you update your CV in the meantime.An hour of work, available today, and it predicts nothing. Preparing is not the same as expecting the worst.
- Whether you keep working normally until you know.The simplest and most underrated choice on the list. Your work is still your work, even when the outcome is uncertain.
Not yours
- Whether your role is on the list.Already decided or not yet, either way without you. This is where your attention wants to go and where it pays the least.
- When the board provides clarity.Their timetable, their pace, their lawyers. Waiting is the only thing to be done here; how you wait is a different question.
- What gets passed around in the corridors.Noise from people who know as little as you do. What is yours: whether you treat that noise as information.
The reasoning. Fear is nearly always about the left column: the outcome, the timing, the list. That is precisely the column where no action is possible. Write out the right column and something concrete usually appears that you can do this afternoon. Not because it changes the outcome, but because it puts you back in the only territory where you are somebody who acts.
