Before planning the wedding details—theme, church, venue, guest list, song while walking down the aisle, and all the works—set a wedding budget and stick to it. According to Huffington Post, a few of the wedding planning mistakes couples commit are: (1) taking the budget lightly, (2) spending too much with limited resources, and (3) choosing impractical destinations. Stick to your wedding budget, manage your expectations, and always choose to be practical. The most important thing here is to have money for the next chapter of your life after getting married. If you can go through this stage in peace, then you two are on the right track to a successful marriage.
