Is there a way to predict the odds of engaging a successful marriage and to choose the right person as a partner? Dr. Sam Hamburg, author of Will Our Love Last, banks on compatability or similarity as the key feature in successful marriages. It's true, opposites attract, but attraction only runs so deep.Regardless of personality differences, truly lasting love stems from compatibility on three deeper dimensions: the practical, sexual, and wavelength. If your goals, values, beliefs, work, or practices affirm and help deepen your autonomous and mutual growth, you can bet your marriage has the best odds.
