According to research, only 8 percent of the people who make New Year’s resolutions actually achieve them. This could be due to people setting unrealistic goals or setting no goals at all. If you want to make a resolution in the New Year and actually stick to it, consider setting a “SMART” goal—one that is specific, measurable, attainable, realistic and timely.
For example, let’s say that your goal is that you would like to take three CrossFit classes per week for 60 days. If you achieve your goal at the end of that 60-day period, you should reward yourself with something worthwhile. Then, keep your original goal going with consecutive SMART goals after you complete each one. Remember that when you set your SMART goal, you should determine your reward then, as well. That way, when you're five weeks in and tempted to throw in the towel, you can set your sights on that specific reward and remind yourself how close you are to getting it.
