A lot of the things mentioned in this tutorial revolve around trust. If you don't trust your partner, you're probably living in a pretty miserable place. Learn to trust your spouse in the same way that you want them to trust in you. Marriage is an enduring opportunity to get to know somebody better and better over many, many years. If you keep an aspect of your personality secret or just closed off, you're probably not getting all that you want out of your marriage. It really does go to show: you get what you give. Have long conversations; make them laugh; share interests, hobbies and occupations; take them somewhere that has personal significance to you; encourage them to get to know your extended family (and do the same for theirs); engage in debate; share fears, doubts, and vulnerabilities; be who you are, not who you think they want you to be. The golden rule is not only important to our idea of morality, it also helps us navigate the sometimes stormy waters of a marriage. The golden rule is that you do unto others as you would have them do to you. All this means is "put yourself in their shoes" before you act. Of course, you need to have the right sort of perspective if you're going to use the golden rule, and you can't lie to yourself about what other people want. If you're unsure about something, ask yourself "What would I want to happen if I were in my partner's position?" This is generally a good exercise for you to engage in. Draw on your faith for strength, and actively seek meaning with your partner on your life's journey. Give yourself to your spouse as much as you give to your god. Maintain your values throughout. Of course, the most important for last: practice good hygiene, look sharp as a tac — inside and outside of the house — and make sure you keep up the same general level of cleanliness that your spouse does. If you care about how well your spouse dresses and how often they brush their teeth, they're sure to care about the same things. And that's the way it should be between two people...

TL;DR in Vietnamese:
Tin tưởng vợ hoàn toàn. Thể hiện tính cách của bạn. Nhớ lấy nguyên tắc vàng. Nếu bạn là người có tín ngưỡng, hãy chia sẻ tôn giáo của mình với vợ. Hãnh diện vì vẻ ngoài của mình.
