The mind is a powerful thing (60-70% of the whole preparation process is the mind). In order to be successful, you need to learn how to CONTROL your mind.
If you've never done a competition before, it would be a wise choice to visit local NPC shows to get a realistic idea of how each category looks. That way you can decide which division would best fit your personal goals.

Don't begin your preparation by overeating the week before you start training and dieting. It'll just make your cravings worse and will add a few pounds you'll have to work harder to lose.
Instead of focusing on food, or on all the things you won't be able to participate in, hone in on contest prep: how good you're going to look, how much fun you'll have and how hard you plan on working.
Every week is going to be different. There will be some weeks that will be bad, but there will also be weeks that will be great. Stay positive through your training and preparation. Focus on the positive. Don't doubt. Don't question. Bottom line: stay focused on goal.
Everyone has drawbacks, but if you stay consistent and stay focused on the big picture, you'll have an affirmative experience. Talk positively to yourself, don't think negatively. Believe in yourself.
When the show is done, don't run straight to a restaurant and start cramming as many burgers as you can. If you focus totally on food, you'll make your body feel pretty crappy.
Control your mind. Come off your diet slowly. Remember, you've just come off a 12-week program and your body will probably be sensitive to foods it isn't used to.
You don't want to create an eating obsession, so keep your mind in a safe place. Try a little bit and keep everything in moderation.
