Whether or not your significant other shares your passion for Stargate SG-1 may seem important, but it's not vital to the success of a relationship. This quality is.
In an interview with TechInsider, couples psychologist and founder of The Couples Institute Dr. Peter Pearson said he believes "sharing core values" is the "holy grail" of a successful relationship, meaning that one thing that's hard to find but makes all the difference.
Explaining his stance, he argued "you can negotiate your interests, but not your values," and pointed out that initial attraction can fade overtime, making a shared, concrete value system way more important. To paint a picture, Pearson cites a couple from one of his workshops:
"He was building this huge house that overlooked a big vista, and she did not want to waste money on this ostentatious, wasteful shlock. She had so much disdain for his life dream of this house — that's a huge collision of values, and that's not an easy thing to compromise on."
