As we prepare to usher in 2015, no doubt many of us have compiled a list of New Year’s Resolutions that we plan to enact the moment we open our eyes and our feet hit the floor on January 1.

Happy New Year

Losing weight, getting in shape, quitting smoking, saving money, organizing and decluttering are all timeless, popular and laudable resolutions. The reason so many people give up on their resolutions is simple: change is difficult, and it requires constant practice.

Rome, as they say, was not built in a day. If you are serious about making lasting changes in your life this year, experts offer advice toward achieving your goals — whatever they might be.

1. Choose a Specific,

Realistic Goal

Every year, millions of adults resolve to “lose weight” or “get in shape” during the next year. Instead of selecting such an ambiguous and vague goal, focus on something more concrete and achievable. For example, you might commit to losing 5 or 10 pounds or running a 5K. Choosing a concrete, achievable goal also gives you the opportunity to plan exactly how you are going to achieve your goal over the course of the year.

2. Stick With Just One Resolution

While you may have a long list of potential New Year’s Resolutions, studies suggest that you should pick just one and focus your energies on it rather than spreading yourself too thin among a number of different objectives.

3. Don’t Wait Until New Year’s Eve

Planning is an essential part of achieving any goal. Experts suggest that you should spend some time planning out how you will tackle a major behavior change. You can start by writing down your goal, making a list of things you might do to achieve that goal and noting any obstacles that might stand in your way.

4. Start With Small Steps

Taking on too much is a common reason why so many New Year’s Resolutions fail. Dramatically slashing calories, over-doing it at the gym or radically altering your normal behavior are sure-fire ways to derail your plans. Instead, focus on taking tiny steps that will ultimately help you reach your larger goal.

If you’ve resolved to run a marathon, start out by going for a jog two or three times a week. Decide to take the stairs in lieu of riding an elevator. If you are trying to eat healthier, start by replacing some of your favorite junk foods with more nutritious foods. Maybe you swap one item of junk food for a healthier option. While it may seem like a slow start, these small changes make it easier to stick to your new habits and increase the likelihood of long-term success.

5. Avoid Repeating Past Failures

Another strategy for keeping your New Year’s Resolution is to not make the exact same resolution year after year. If people think they can do it they probably can, but if they’ve already tried and failed, their self-belief will be low. If you do choose to reach for the same goals you’ve tried for in the past, spend some time evaluating your past results. Which strategies were the most effective? Which were the least effective? What has prevented you from keeping your resolution in past years? By changing your approach, you will be more likely to see real results this year.

6. Remember That Change Is a Process

Those unhealthy habits that you are trying to change probably took years to develop, so how can you expect to change them in just a matter or days, weeks or months? It may take longer than you would like to achieve your goals, but remember that this is not a race to the finish. Once you have made the commitment to changing a behavior, it is something that you will continue to work on for the rest of your life.

7. Don’t Let Small Stumbles Bring You Down

Encountering a setback is one of the most common reasons why people give up on their New Year’s Resolutions. If you suddenly relapse into a bad habit, don’t view it as a failure. The path toward your goal is not a straight one, and there are always going to be challenges. Instead, view relapses as learning opportunities.

If you are keeping a resolution journal, write down important information about when the relapse occurred and what might have triggered it. By understanding the challenges you face, you will be better prepared to deal with them in the future.

8. Get Support from Your Friends and Family

Yes, you’ve probably heard this advice a million times, but that is because the buddy system actually works. Having a solid support system can help you stay motivated. Explain what your goals are to your close friends or family and ask them to help you achieve your objectives. Better yet, enlist the help of others by joining a group that shares your goal.

9. Renew Your Motivation

During the first days of a New Year’s Resolution, you will probably feel confident and highly motivated to reach your goal. Because you haven’t really faced any discomfort or temptation associated with changing your behavior, making this change might seem all too easy.

After dealing with the reality of dragging yourself to the gym at 6 a.m. or gritting your teeth through headaches brought on by nicotine withdrawal, your motivation to keep your New Year’s Resolution will probably start to dwindle. When you face such moments, remind yourself of exactly why you are doing this. What do you have to gain by achieving your goal? Find sources of inspiration that will keep you going when times get tough.

10. Keep Working on Your Goals

By February, many people have lost that initial spark of motivation that they felt immediately after making their New Year’s Resolution. Keep that inspiration alive by continuing to work on your goals, even after facing setbacks. If your current approach is not working, reevaluate your strategies and develop a new plan.

Consider keeping a resolution journal, where you can write about your successes and struggles. Write down the reasons why you are working toward your goal so that you can refer to them during times when you feel uninspired and unmotivated. By sticking with it and working on your goal all year long, you can be one of the few able to say that you really did keep your New Year’s Resolution.
