What makes some marriages work and others not?

One of the classes in my advanced coach training talked about relationships and how best to coach people around relationship challenges. Some of the content came from John Gottman's book "7 Principals That Make Marriage Work". Apparently, his research applies (with some language modifications) to relationships at work or those with friends and family members - so it's very powerful information.

What's particularly relevant of his research to coaching is that hey says that 69% of the issues in relationships are perpetual - meaning they happen time and time again. Boy what a great thing to work on with your coach. 

Here's a short video by John about his research. If you want more, check out Parts 2-4 or one of his longer videos on YouTube or pick up a copy of his book.
