I used to think the spark meant something.

You know the feeling — someone texts you back after hours of silence and your whole body lights up. They cancel plans but then send a message at midnight that makes you forget they ever cancelled. They are warm one day and cool the next, and somehow the unpredictability makes you want them more.

I spent years calling that chemistry. It was not chemistry. It was my nervous system confusing relief with connection.

Here is the question that changed everything for me:

"If this person's effort stayed exactly at this level forever, would I still want this?"

Not their potential. Not who they are on their best day. Not the version of them that shows up after you have pulled away and they suddenly realize they miss you. Their average effort. Their Tuesday afternoon effort. The effort that exists when nobody is chasing anyone.

Most of the time, the honest answer was no.

And that was the problem — I was not falling for people. I was falling for the gap between their best moments and their worst ones. The inconsistency itself was creating the intensity.

There is a name for this. It is called intermittent reinforcement. Slot machines use it. So do people who are emotionally unavailable. The reward is unpredictable, so your brain becomes obsessed with trying to earn it.

Once I saw that, I could not unsee it.

I started tracking effort instead of analyzing words. I stopped asking "what did they mean by that text?" and started asking "who initiated contact this week, and how many times?" I stopped trying to decode mixed signals and started treating mixed signals as the answer.

A mixed signal is not a puzzle to solve. It is a person showing you, clearly, that their interest is not consistent.

The shift is not about becoming cold or transactional. It is about learning to feel the difference between someone who is genuinely interested and someone who only feels exciting because they are hard to reach.

Mutual interest is quieter than the chase. It does not give you the same adrenaline spike. But it gives you something better — it gives you peace. And from that peace, you make decisions you do not have to recover from.

If any of this sounds familiar, I wrote a guide about it. It is a 14-day filter system with scorecards, decision matrices, and the one question above built into a daily practice.
