First Things First: This is the No. 1 phrase used in successful relationships

How often do you say “thank you” to your spouse or significant other?

If this question makes you feel uncomfortable, guilty or maybe even asking the counter-question, “For what!?,” you’re not alone.

A recent 50-year study completed by The Gottman Institute found that the single most important phrase couples can use in their relationship is “thank you.” After observing 40,000 couples during therapy sessions, clinical psychologists John and Julie Gottman found relationships with an “enthusiastic culture of appreciation” were more likely to be successful for a lifetime than those who don’t regularly practice gratitude.

Think back through your last couple of days or weeks. How often did you say “thank you” to a total stranger? Of course, you thanked the person who held the door open for you or the waiter who refilled your glass. Do you feel the same urgency to say “thank you” to your partner? Do you express your gratitude when they empty the dishwasher, finish the laundry or listen while you vent about your day?

In full transparency, after completing this simple exercise, I realized I don’t say “thank you” to my husband as often as I should. It’s not that I’m not grateful for him. Life is just busy. There are a million things on my plate, and I don’t pause long enough to show him how appreciative I am.
