Consider that your wedding day is not actually for you at all. It’s for your families, friends, and all the invited guests. So they can dress up, eat a fancy meal, smile at some cameras, and be seen smiling at some cameras.
For you, it’s just a day you need to get through to reach your real purpose, your goal, your happily ever after: Which is BEING married, and living the rest of your life with someone you love.
