1. Write it Down! Seeing your resolution clearly articulated in ink, on paper can have a tremendous effect on your feeling of commitment to it. Or, type it out on your laptop or smartphone's version of sticky notes so that you'll see daily when you turn your device on.
By confiding your resolution in a friend, you'll make it seem more concrete. After having told someone, you'll probably feel obligated to seeing your goal through, and that could be a really motivating factor that can help you to keep your resolution.
