“Don't say negative things about your spouse and children.”

“Don't cohabitate. Don't fornicate. Don't look at pornography. Don't create a standard of beauty. Have your spouse be your standard of beauty. This is one of the great devastating effects of pornography: you lust after people and compare your spouse to them. It's impossible to be satisfied in your marriage if you don't have a standard that is biblical; that standard is always your spouse.”

“People are in one of two states in a relationship,” Gottman went on. “The first is what I call positive sentiment override, where positive emotion overrides irritability. It’s like a buffer. Their spouse will do something bad, and they’ll say, ‘Oh, he’s just in a crummy mood.’ Or they can be in negative sentiment override, so that even a relatively neutral thing that a partner says gets perceived as negative.”

“Say NO to negativity and say YES to positivity. Negativity has no place in your life.”

“If you want your children to improve, let them overhear the nice things you say about them to others.”

“We could not be fulfilled if we weren't inauthentic some of the time—inauthentic, that is, in relation to such things as our passing desires to throttle our children, poison our spouse, or end our marriage over a dispute about changing a lightbulb.”
