Keep it small. While you may be tempted to invite everyone, their brother, and their brother's neighbors, to your wedding, just don't. The more people you invite, the less time you have to spend with each of them and the less memories you'll get to create. Obviously, a smaller wedding is generally cheaper as well. PS: If you invite too many people, you'll spend so much time talking to them all that you won't get to eat. Which would be awful.
Take a deep breath. Although the accepted maxim in today's society is that your wedding is the "most important day in your life," it really ISN'T. You will (hopefully, if you don't act like a bridezilla) live long enough to have many other days which are just as important to you. While it is an important day, it is not the end-all-be-all for your life, so don't treat it like it is.
Change your idea of perfect. When we grow up, we all picture the "perfect" wedding day in our minds, and let me tell you, if you're expecting your wedding to be like that, prepare to be disappointed. Things will go wrong. Things will break. Things will be lost. If you get stuck on everything that is going wrong, you will lose focus on everything that is going right...and as Carrie said to Charlotte, you'll miss it!
It's not all about you. Despite everything that you've grown up hearing and everything that people may say to you, your wedding is not YOUR day. Your wedding is, at the very least, about two people - yourself and your fiance. Include him in the planning, and let him have a silly cake if he wants it. Let him dance as oddly as he wants to, and don't make him wear a tux if he doesn't want to. Remember, after the wedding the two of you have to live together so he is the last person you want to alienate!
Yes, that is a picture of my groom's cake...it was a fish, and YES we picked it out to be red velvet on in the inside to look like blood. And you know what? It was a hit and everyone loved it, including me! Have fun! This one is obvious...just have fun! Stop trying to make it be something that you imagined and just let it be what it is!
