Drs. Charles and Elizabeth Schmitz were my first guests. For 27 years, they have studied the ingredients of successful marriages on 5 continents and over 40 countries. They co-authored of Building a Love That Lasts: The 7 Surprising Secrets of Successful Marriage. Then I spoke with Mary Treacy O’Keefe, author of Thin Places, about soul friends. What makes these relationships so rare and special? How do you find them? Or do they just happen? Does it work to seek them?
