The Simon Sinek 3+1 formula breaks relationship compatibility into core elements that can determine whether a couple is simply good or truly great together, according to the author and speaker.
Sinek, founder of The Optimism Company, said he developed the approach after years of observing what helps long-term partnerships thrive. The model points to three central compatibilities that can fluctuate over time, plus a fourth factor that sits outside a couple’s control.

The three core components are:
- Intellectual compatibility. Partners feel mentally engaged, enjoy each other’s company, and have conversations that keep them connected. It is less about matching IQs and more about sharing curiosity and interests.
- Emotional compatibility. Both people are willing to be open, vulnerable, and emotionally available, creating a foundation of trust and care.
- Sexual and creative compatibility. A satisfying intimate life that benefits from imagination and playfulness. Sinek links sexual spark and creativity, noting both draw on a similar imaginative drive that helps couples avoid stagnation.
He adds a fourth, bonus factor: circumstances. External realities such as timing, distance, or existing commitments can influence whether an otherwise strong match can succeed.
Sinek said a relationship might feel solid with one and a half or two of the three pillars, but the strongest partnerships build all three. They will not always peak simultaneously, he noted, but together they can help couples navigate ups and downs. Circumstances can still tip the balance, such as when an ideal partner lives far away or timing is off.
Mistaking infatuation for compatibility
Sinek cautioned that early intensity can mislead people into believing they have found a perfect match when only one or two factors are strongly present. Early attraction, he said, can reflect dopamine-fueled infatuation rather than durable compatibility. He encouraged giving promising partners time to see whether the full set of compatibilities develops, even when there is not an instant spark.
He pointed to relationships that grow from friendship or shared work over years, where feelings deepen without dramatic early fireworks. Once the initial rush fades, it often becomes clearer whether a couple aligns across intellectual, emotional, and sexual-creative dimensions.
Striking a balance
For couples seeking better balance, Sinek recommends noticing daily habits that erode connection. Setting aside phones during dinner or dates can help restore attention and conversation. He emphasized that in today’s fast-moving, gratification-driven dating culture, long-term success still depends on nurturing all three core areas over time.
“Sometimes we get infatuated because we find one or two of those things, but for it to really last, it takes all three.”
Sinek added that even sexual connection may emerge later as emotional closeness grows. He urged couples not to overvalue a single strong factor early on, but to stay aware that all three dimensions matter as they naturally ebb and flow alongside life’s circumstances.
For some, that perspective may resonate with real-life experiences of partnership at different life stages, like those described in finding love after 60.
