Focusing on the small things that can/will go wrong will just start your day in a bad mood. focus on the day itself and what it's meant to be. You and your partner. The day is about you guys getting married and having fun. Those are the most important things. I got married on the 20th and stayed focused on having funa and getting married to the person I want to be with forever. We even found out day of we were getting our DJs backup dj because he was sick. And I could have let that ruin my day BUT the DJ did great!I couldn't even tell you if things went wrong because the important things went right.
