These resolutions are usually prompted by things we want to change in our lives and we create an action plan to make the change. Some will want to quit smoking, lose weight, gain weight, stop drinking as often, exercise more, spend time with family, drink more water, start saving money, read one book a month etc.
In order to really follow through with your New Year's Resolution, you need to devise a plan. Sit down and brainstorm. Think realistically at how you would go about following through with the resolution.
For example if your New Year's Resolution is to start eating breakfast every morning you have to ask yourself if you can realistically wake up an hour earlier every morning to make breakfast. If you want to start attending Sunday Services, you need to make sure nothing conflicts with the time slot on Sundays.
For the very many who will create a resolution based on diet and exercise, you really need to determine what goals/results you desire then choose what means to obtaining the results you can physically do and most importantly determine how often you can realistically do it. Don't say you will work out in the gym 5 days a week, if you work 40+ hours, have children, and can't afford a gym membership. You are setting yourself up to fail before you even began. There are many exercises that can be done in the home or in the yard. Working out 2-3 hours a week and being able to remain consistent is much better then aiming for 5 and only making 2, because you will lose confidence in yourself if you continuously fail to work out 5 days and that's not necessary when you are the one in control of your resolution.
You have to keep it real in order to Keep It Healthy.
