Similarity does not necessarily mean compatibility.
Traditional matchmaking focuses on individual characteristics: age, education, social background, interests, lifestyle, and the person's idea of an ideal partner.
This information matters. On its own, however, it does not answer the more fundamental question:
Can two people create a relationship that supports the life they want to build and sustain over time?
Compatibility emerges where not only two people's characteristics meet, but also their values, priorities, life architecture, expectations, decision-making styles, and future direction.
