Whether you are just beginning your relationship or you have had many years together, you can benefit from implementing the following suggestions on making a good marriage great. Marriage is like a living entity and it is either nurtured and growing or it is neglected and crumbling. Hopefully, like mutual funds, over time the trend will be upward. Unfortunately in marriage you do not get to coast for long. The good news is that making your marriage great is simple, not to be confused with easy.

Be more concerned about we than me. Selfishness is a relationship killer. Taking your partner's thoughts and feelings into consideration at all times helps you make choices that benefit both of you.
Be realistic about expectations. Romance novels are not a good source for relationship templates. What expectation are realistic for your relationship, is something the two of you need to agree upon. Your relationship is unique and needs to work for both of you.
Reduce stress. Finding ways to reduce work and other stress can improve your marriage; a happy marriage also makes the rest of your life easier as well.
Reminisce. Spend time now and then talking about how we met, started dating, fell in love. Don't worry if your story is not overly dramatic or romantic. Enjoy the fact that it is your story.
Live now. Don't get stuck ruminating about your wedding day, good or bad, focus on making your life together. Be present now, enjoy each day you have together and plan for your future.
Pay attention to the little things. Daily acts of kindness and consideration are the live-blood of any extraordinary relationship.
Solve the solvable problems. Address the minor issues, so they don't build up.
Keep or find your sense of humor. There is a quote that says, “Parenting without a sense of humor, is like being an accountant who sucks at math.” This applies doubly to marriage.
Focus on the positive. Enough said.
Be the change you want in your relationship. Take ownership of your contributions to problems and control what you can control, your words and behavior.
Be empathetic. Be willing to see things from your partner's point of view.
Make time for each other NOW. Consistency is the key, no matter what else is going on in your life, make time for each other. There may be occasions when it may not be a lot of time, but when making time for each other is your habit, you will know that you can count on each other.
