1. Plan Early
If you're getting married in a year, don't wait until three months out to try and find a photographer or a dj. I have a friend who took this laid-back approach to wedding planning, and in the end, it was much more stressful for her. I'm not implying that the first person you should call right after your fiance gets up from bended knee is a florist, but the sooner you find your vendors and sign contracts, the less you have to worry about come crunch time. There are several wedding planning trackers online that offer guidelines about what you should have accomplished from 12 months out, up to the day of the wedding.
2. Make a List
Most couples know to create a budget for the wedding, but many don't create lists of specific things they have to have for the day. It can be helpful if you and your fiance comprise a list of what is important to you about the wedding day, followed by a list of what you're willing to compromise on. Carry the list with you (mentally or physically) when you're meeting with vendors, that way there is something set in stone and you won't have to stress out about whether or not you should splurge on designer table linens.
