In the initial stages chemistry is very important
In later stages in a relationship communication is the most important thing.
Education will naturally change someone’s mindset and so you have more in common to talk about, but that’s just one of the many topics that can be talked about, hobbies, dancing, spirituality, philosophies, technical things, etc.
I think there is way too much emphasis on education/career, the key to a successful relationship is not how much money someone makes (as you see many unhappy wives with rich educated husbands that are never home and never have time for loving their wife). Happiness is a state of mind. Similar education is a minute aspect of compatibility as you might have one more thing to talk about. chemistry and communication are important. Education is only a small factor of compatibility and i definitely wouldn’t put it on some list of requirements about who you date.
