New Years Resolutions

What's your New Years Resolution? Mine is to hit the gym more. Every year at this time we are all trying our best to fulfill our resolutions. And it seems to go smoothly at first, but by like march they always seem to be thrown out the window? Why is this? Do we set resolutions that are unattainable or do we simply just give up? It's always the thing to talk about around the New Year so you'd think we'd put more effort into actually accomplishing them. Should we strive for something that is easily accomplished or should we go big? I guess if we had the answer then we wouldn't keep making these resolutions that we don't keep.
