When was the last time your partner thanked you? Better yet, when was the last time YOU thanked your partner? I have to say, Hus does so much for me on a daily basis that I could never truly thank him enough. But I try. At least once every single day, I tell Hus "thank you" for something specific (and that doesn't include all of those things I should already be thanking him for-- like for holding the door or getting me something) or I'll say that I appreciate him for his general contributions to our family and marriage.
I learned at a young age that appreciation was not only key to building relationships with other people, but that it also has the ability to make you a much happier individual. When you thank people, especially about positive things that are happening in your life, you begin to realize just how great your life is.
Think about what your spouse does for you and thank him or her. Today. Go ahead, you can do it.
