My best advice to couples considering marriage is to take the time to really get to know each other and have honest, open conversations about what you both want out of life. Marriage is a huge commitment that will affect both of you for the rest of your lives, so it's important to make sure that it's something that you both truly want and are ready for. Also, don't forget to put in the effort even after marriage! Communication and quality time together are key ingredients for a successful and happy marriage.
