Five Strategies for Highly Effective New Year's Resolutions

Creatas/Thinkstock(NEW YORK) -- Jeremy Dean doesn't like the idea that you've made a New Year's resolution yet again this year.  But as a research psychologist at University College London, he knows you've gone ahead and made one anyway.

"Most resolutions are too vague, too hard and too spontaneous," he said.  "You're better off taking the time to think things through and putting the necessary preparation into place so you have a chance of succeeding."

Still, if you're going to do this thing, he wants you to do it right.  Here are five strategies from Dean's new book, Making Habits, Breaking Habits, for making your resolutions stick.

Balance Good and Bad

A positive outlook is a good start to a resolution but it will only get you so far, Dean said.  You also need to think about everything that can stand in your way.  Psychologists call this technique "mental contrasting." It works, Dean said, because it fires up motivation and because it better prepares you for what can go wrong.

Focus on Process

Fantasizing about being rich or thin can be oddly de-motivating, because it allows you to taste just enough success to stop you from taking action.  "You're a lot more likely to reach your goals if you focus on the steps you need to take to get there rather than the end result itself," Dean pointed out.

Think "If/Then"

Resolutions that are too vague are doomed to failure, Dean says.  But so are ones that are hyper-specific.  Strike the happy medium by turning to resolutions into "if/then" statements.

Let's say your aim is to live a more active lifestyle.  Starting off with the idea you'd like to walk the stairs more often, craft your goal like this: If I come to an elevator, then I will take the stairs or get off one floor early and take the stairs from there.

Such a statement links the actions you wish to take (walking stairs) with a common situation (coming to an elevator), increasing the likelihood that you'll follow through because it allows you to hook your habit onto a chain of events in your day that's already taking place.

Replace Don't Erase

When most people decide to address a bad habit such as smoking or binge eating, they usually try to squelch it.  You're better off trying to replace the bad habit with a better one.  So, instead of trying to completely terminate a habit like nighttime snacking, Dean suggested replacing the junk food for which you normally reach with some fruit.

Keep on Repeating

Just how long does it take to create a new habit?  In a study carried out at University College London, 96 participants were asked to make an everyday behavior such as drinking more water, eating more fruit or exercising into a regular practice.  More than half the participants couldn't hack it and quickly dropped out, but those who kept at it took an average of 66 days before the new routine became automatic and subconscious.

There was some variation: Simple tasks such as drinking a glass of water before breakfast took only about 20 days to take hold.  Exercise proved to be the most stubborn goal; one participant who lasted until the end of the study took 84 days to make doing 50 sit ups a day a regular occurrence.

Dean said that each time you repeat the same action, consider it a mini-victory and know that it moves you one step closer to making your resolution an official habit.
