New Year's Resolutions... What Are They good For???

So every year we think about a better way to better our lives by changing something we did last year that we don't want to do this year. We make these Resolutions and begin to follow them and then we never finish the year out. My Resolution this year is to have better study habits. I feel that this semester I didn't do as much studying as I should have and I waited until the last minute. Well this year I plan to change all this around I plan to take more time to study so I won't have to cram for tests or papers the day before they're due. What's your New Years resolution and how to you plan on maintaining this through the year?
