Enlist help from friends and family where possible. Everyone likes to be involved in a wedding and you do not have to do it all yourself.
Make a list of everything you will need to bring with you on the big day. Gather everything in advance and put it in one spot so that you don't have to search for an essential item at the last minute.
Do not make drastic changes to your hair color for your wedding. If you already color or highlight your hair, have it touched up a week before the day.
