Thankfully, Cami and I have also been blessed with a great deal of happiness in our marriage and so I have not only observed but experienced first hand a happy marriage.
When I was a sophomore in high school I took a chemistry class. I loved that class. Learning has always been a passion of mine and I am perennially curious. I ask questions about everything and want to know how everything works and why.
My chemistry teacher knew this about me and, about midway through the year, told me that when she prepared her lesson plans she would do so with me in mind. She told me that she always knew that when a new concept was presented my hand was going to shoot into the air and I would ask why.
I still do it. My bosses at work must get tired of me because I haven't changed. I know that Cami sometimes gets frustrated because I am constantly trying to figure out the "why" behind everything.
As I have watched married men and women through my life, and when I realized that Cami and I were VERY happy, I have asked "Why? What makes a marriage happy?"
I'm still working on the ENTIRE answer but after all of my observation and study I am absolutely confident that for me, and other happily married men, there is a simple mathematical equation that explains how to achieve happiness in marriage. It is:
A HAPPY WIFE = A HAPPY LIFE
That's it. This is the #1 secret to being happily married (for husbands, that is). Work to make your wife happy and you will be too.
