After 4 years of marital life I could make a list of potions for a marriage out of my experiences. May be after some more years I will have to rewrite again by adding some more points to the following. 
 
1. A marriage is the oldest and God formed institution. 
2. A marriage is a covenant where couples have to lose everything to gain.
3. A marriage built on godly principles can last forever.
4. A marriage where love is sacrifice can be called as the marriage in truest sense.
5. A marriage relationship is not a partnership where the partners share 50-50 but it’s a friendship where they share 100-100.
6. EGO less partners make the best marriage on earth.
7. A true marriage has no ‘personal space’ in it.
8. A constant growth of love between the spouses keeps a marriage safe and secure.
9. Silence is not GOLD in a marriage relationship; in fact it’s a WALL.
10. Appreciation for each other is a nourishment to make a marriage healthier.
11. Humility teaches the spouses to become humble. 
12. Sex is secondary; love is primary in a marriage relationship.
13. A marriage is a bond, not bondage.
14. The spouses love to take responsibility in a true marriage.
15. The sex libido of the spouses’ surges only for each other in a true marriage. 

Dear Spouses! Please take a good dose of the above potions to stay healthy in your marriage life. Trust me it’s difficult but not impossible. All the best!
