Trick two: "not quite right"
Perfection has a younger sister who catches not the single anymore, but those already in a relationship. There's a lot of good between you: warmth, reliability, shared plans. But there's something that triggers and angers you — a trait, a habit, a manner. And the mind slips you arithmetic that sounds perfectly reasonable: why work on a relationship for years when you can find someone who fits at once — without this trait, without this irritation, ready-made whole?
The trick hides in two places. First: the "one who fits at once" is simply a person you haven't yet lived with long enough to reach the friction. Unfittedness shows up not in the first months but at depth — the same depth where you are now. Any two people, having lived down to household, fatigue and vulnerability, find zones where they are hard for each other. With the "right one" there will be no absence of the irritating — there will be a different set of it. Having lived with them down to the same depth, you'll find yourself at the same point, minus the years and minus everything accumulated: the trust, the history, the fitting already done.
Second — and here the compass comes back to mind: half the triggers aren't about the partner at all. What angers you isn't the act itself but what it lands on in you: an old wound, a parental script, unprocessed fatigue. A trigger like that will move to the next person with you, safe and sound — and will find something to fire on. Replacing the partner won't solve it; it's solved only on your side.
In fairness: real incompatibilities exist too — different answers to the big questions: children, fidelity, willingness to invest, basic respect. One person's work doesn't fix those, and enduring them for years is no virtue. The distinction is this: a trigger is an irritation that grows out of your wounds and fatigue and shifts with your state; an incompatibility is a calm, stable "we answer the big questions differently" that sounds the same in any mood. The first is fixed by conversation and work — and that's a transferable skill that stays with you in any relationship. The second isn't fixed at all.
"Finding someone who fits at once" means finding someone you haven't yet reached the friction with. Your triggers will move in with them, along with you.
