Tolerance? That's what makes a "successful" long-term relationship? That's the best we can do in this lifetime, finding someone we can tolerate?! That's not living a full life!

Here's a hint: how often do you look deeply into your partner's eyes? Yes, the way you did when you were dating. In most long-term relationships, it normally stops happening. It's one of the defining characteristics of a relationship that has a lack of commitment to growing in intimacy. Figure out how to grow in intimacy and you don't have to worry about simply tolerating another human.

I follow a more esoteric spiritual path, but there is a mainstream book that is well-regarded, "Passionate Marriage", that touches on some of the techniques folks have used to build successful enduring relationships.
