Do you have trouble finding things to rave about in your spouse. Here's a quick tip to change everything: find the negatives and recast them as positives. Is your husband or wife impatient? Recast that quality in a positive way, "My husband is intense." Do you think your wife is a slob? Recast that quality in a positive light: "My wife is casual." I know it may seem a bit loony at first but when you understand the wisdom behind it, it starts to make sense. Research shows that your perceptions not only color your current reality, they actually altar your relationship and create your future reality.
What I am suggesting is this: find the most generous explanation for your spouses behavior and believe it. This is actually a quality of Biblical love, "Love believes all things."
Give it a try! It could change your marriage. It is better than complaining. :)
